6 best night sky events in April 2026
- April 2 — Full Moon. April’s Full Moon, known as the Pink Moon, reaches its peak at 02:12 GMT. No, it won’t actually turn pink — but it’s still the month’s brightest Moon.
- April 3 — Greatest elongation of Mercury. Mercury reaches its greatest western elongation and puts on its best morning show of the year. It’s especially good from the Southern Hemisphere, where the planet climbs higher before sunrise.
- April 4 — Comet C/2026 A1 (MAPS) at perihelion. This comet has been building suspense all through March, and in April we finally get the finale: it could become bright enough to see without binoculars, or it could fall apart near the Sun and leave us with no show at all. Either way, comet watchers will be paying attention.
- April 18 — 4-planet alignment. Mercury, Mars, Saturn, and Neptune bunch up in the pre-dawn sky for a small but neat planet parade. The view is better from the Southern Hemisphere, but early risers everywhere can at least try.
- April 19 — Comet C/2025 R3 (PanSTARRS) at perihelion. PanSTARRS looks a bit less dramatic than MAPS, but also less likely to let us down. After perihelion, it may brighten enough to become a very nice target — and possibly even a naked-eye one.
- April 22 — April Lyrids meteor shower peak. The Lyrids are April’s main meteor shower and can bring up to 18 meteors per hour at peak. Not a meteor storm, but definitely enough to make staying up late feel worth it.

Moon phases in April 2026
Here are the main Moon phases in April 2026:
- Full Moon: April 2, 02:12 GMT
- Last Quarter: April 10, 04:52 GMT
- New Moon: April 17, 11:52 GMT
- First Quarter: April 24, 02:32 GMT

Full Moon on April 2: Pink Moon
The Full Moon reaches its peak on April 2, 2026, at 02:12 GMT. This month’s Full Moon is traditionally called the Pink Moon — not because it actually turns pink, but because the name is linked to the pink blossoms of wild ground phlox, one of the earliest flowers of spring in North America. So no, the Moon itself won’t look like cotton candy, but the name is nice anyway.
This Full Moon is also the Paschal Full Moon, which means it helps determine the date of Western Easter. By the traditional rule, Easter is celebrated on the first Sunday after the first Full Moon following the March equinox. In 2026, that puts Easter on April 5.

New Moon on April 17: best dark-sky night
The New Moon occurs on April 17, 2026, at 11:52 GMT. Around this date, the Moon stays out of the way, leaving the sky nice and dark for faint targets. The period from April 14 to April 20 — including the night of the New Moon itself — is a great time to look for objects that don’t appreciate moonlight, such as galaxies, star clusters, nebulae, and comets. So if you’ve been meaning to hunt down something dim and fuzzy this month, this is your window.
Planets visible in April 2026
April 2026 brings a few nice treats for planet watchers. Mercury reaches its greatest elongation of the year and is especially favorable for observers in the Southern Hemisphere. The most interesting planetary story of the month unfolds before sunrise in mid-to-late April, when Mercury, Mars, Saturn, and Neptune gather in one small area of sky.
Planet visibility in April 2026: Northern Hemisphere
- Mercury (Aquarius, Pisces, Cetus, Pisces; mag from 0.2 to −0.7): Mercury appears in the morning sky, but only briefly — it rises about half an hour before sunrise. Through a telescope, you can watch the planet’s disk change during the month, from a crescent to a half phase and then to an almost full disk.
- Venus (Aries, Taurus; mag −3.8): Venus continues its best appearance of 2026. It shines brightly in the evening sky all month long and stays visible for about an hour and a half after sunset.
- Mars (Pisces; mag 1.2): Mars peeks above the horizon before sunrise. At the beginning of April, it rises only about 20 minutes before the Sun, but the viewing window slowly improves as the month goes on.
- Jupiter (Gemini; mag −2.1): Jupiter is well placed in the evening sky. It stands highest shortly after sunset, then gradually sinks lower and sets late at night.
- Saturn (Pisces; mag 0.9): At the start of the month, Saturn rises almost together with the Sun, so it’s basically lost in the morning twilight. By the end of April, it begins to move a bit farther from the Sun and becomes easier to spot before dawn.
- Uranus (Taurus; mag 5.8): Uranus can be seen in the evening sky for a couple of hours after sunset. Under dark, moonless skies, it is technically possible to spot it with the naked eye, but binoculars or a telescope will make the task much more realistic.
- Neptune (Pisces; mag 7.9): Neptune begins the month too close to the Sun to observe, but by mid-April it starts to appear low in the morning sky before dawn. You’ll need a telescope to see it — and, as always with objects near the Sun, be careful not to point your optics too close to sunrise.
Planet visibility in April 2026: Southern Hemisphere
- Mercury (Aquarius, Pisces, Cetus, Pisces; mag from 0.2 to −0.7): Mercury is well placed in the morning sky throughout April and can be seen for about one and a half to two hours before sunrise. Through a telescope, you can watch the planet’s disk change during the month, from a crescent to a half phase and then to an almost full disk.
- Venus (Aries, Taurus; mag −3.8): Venus is briefly visible in the evening sky, staying above the horizon for less than an hour after sunset.
- Mars (Pisces; mag 1.2): Mars is visible in the morning sky for about an hour and a half before sunrise.
- Jupiter (Gemini; mag −2.1): Jupiter is well placed in the evening sky. It stands highest shortly after sunset, then gradually sinks lower and sets by late evening.
- Saturn (Pisces; mag 0.9): Saturn rises about an hour before sunrise and can be seen low in the morning sky.
- Uranus (Taurus; mag 5.8): Uranus is visible in the evening sky for about an hour after sunset. Under dark, moonless skies, it is technically possible to spot it with the naked eye, but binoculars or a telescope will make the task much more realistic.
- Neptune (Pisces; mag 7.9): Neptune rises about an hour and a half before sunrise and is visible in the morning sky. You’ll need a telescope to see it — and, as always with objects near the Sun, be careful not to point your optics too close to sunrise.
April 3: greatest elongation of Mercury
On April 3, 2026, at 22:32 GMT, Mercury reaches its greatest western elongation, appearing 27°49′ west of the Sun. In plain English: this is one of the best chances all year to spot the Solar System’s most elusive planet. Look for Mercury low in the pre-dawn sky in the constellation Aquarius, and make sure you have a clear eastern horizon — the planet doesn’t climb very high. This is the best morning apparition of Mercury in 2026, especially for observers in the Southern Hemisphere.
Mercury is bright enough to be seen without a telescope, but it can still be tricky to spot, so timing matters. Start looking as morning twilight begins, before the Sun gets too close to the horizon.

April 18: 4-planet alignment
On and around April 18, 2026, Mercury, Mars, Saturn, and Neptune gather close together in the pre-dawn sky, forming a compact little planet parade.
The best place to watch this lineup is the Southern Hemisphere, where the planets rise higher above the horizon and stay visible in a darker sky for longer. In the Northern Hemisphere, the alignment is much trickier: the planets sit low in the brightening dawn, especially above about 30°N, so you’ll need a very clear eastern horizon and a bit of luck.
As for what you can actually see, Mercury, Mars, and Saturn should be visible to the naked eye under good conditions. Neptune is the hardest one of the four — it’s too faint to see without binoculars or a telescope. Since the whole lineup appears low in the brightening dawn sky, be careful not to point your optics at the Sun.
You also don’t have to catch it on exactly April 18. The planets stay grouped for several mornings around that date, so think of it less as a one-day event and more as a short viewing window for early risers.

Constellations in April 2026
April is a good month for constellation hunting: some of the season’s brightest star patterns are easy to spot, while a few fainter ones give you something to work for. Here are some of the best constellations to look for in April evenings.
April constellations in the Northern Hemisphere
In the Northern Hemisphere, April is a great time to look for Leo, Ursa Major, Hydra, Crater, Leo Minor, and Sextans. Leo is one of the easiest constellations to recognize thanks to the Sickle asterism, which looks like a backward question mark, with Regulus marking the bottom of the shape. Regulus also forms part of the Spring Triangle, a large seasonal asterism that is easiest to spot in April. Ursa Major remains a favorite thanks to the Big Dipper. Hydra, the largest constellation in the sky, stretches low across the horizon, with Crater riding on its back. And if you’re in the mood for a bit of a challenge, try spotting the fainter constellations Leo Minor and Sextans nearby.

April constellations in the Southern Hemisphere
In the Southern Hemisphere, April offers a mix of familiar constellations and a few fainter targets. Look for Leo, Hydra, Crater, Antlia, Sextans, and Chamaeleon. Leo and Hydra are the easier ones, while Chamaeleon and Antlia are much fainter and better suited to dark skies. Chamaeleon is a true southern constellation and can’t be seen from most of the Northern Hemisphere, so southern observers get an exclusive here.

Comets in April 2026: two of the best comets of the year
April 2026 is unusually generous to comet watchers: at least three comets may be observable this month, depending on location and equipment. Two of them — C/2026 A1 (MAPS) and C/2025 R3 (PanSTARRS) — may even become visible to the naked eye.
Safety note: Never use binoculars or a telescope to search for a comet or planet close to the Sun. Wait until the Sun is fully below the horizon.
The real wild card is C/2026 A1 (MAPS), a rare sungrazing comet that reaches perihelion on April 4 and passes closest to Earth on April 6. On paper, it looks like the star of the month: brightness forecasts are impressive, and if everything goes right, it could turn into a striking naked-eye object in the twilight sky. In practice, things are a bit messier. MAPS will be lurking very close to the Sun, which makes it tricky to observe, especially from the Northern Hemisphere. And because it’s a sungrazer, there’s always the chance that it simply won’t survive its close solar encounter. If it does make it through perihelion intact, observers in the Southern Hemisphere should get the best views, with the comet appearing low in the western sky after sunset. The Northern Hemisphere may also get a shot, but the comet will sit frustratingly low above the horizon.
If MAPS is the chaotic one, then C/2025 R3 (PanSTARRS) is the more reliable candidate. It reaches perihelion on April 19 and makes its closest approach to Earth on April 26. Its predicted brightness is a bit more modest, but it has a better chance of putting on a decent show. After perihelion, PanSTARRS could brighten to the edge of naked-eye visibility — and if we get especially lucky, it may become even more impressive for a short time. Before perihelion, it favors the Northern Hemisphere; in late April and into early May, it moves into a better position for the Southern Hemisphere.
There’s also 88P/Howell, which will remain visible from the Southern Hemisphere through the end of April. This one is far less dramatic than MAPS or PanSTARRS and is expected to stay a telescopic target, but it still adds to the month’s comet lineup. In other words, even if the headline acts decide not to cooperate, April won’t leave comet hunters completely empty-handed.
Place your bets: which comet will be best in April — MAPS or PanSTARRS?

Meteor showers in April 2026: the long-awaited Lyrids
April brings two main meteor showers: the more reliable April Lyrids and the less predictable Pi Puppids. The Lyrids are the main event here, while the Pi Puppids are more of a “maybe something cool will happen” kind of shower.
-
April 22 — April Lyrids. The month’s main meteor shower peaks on April 22 and can produce up to 18 meteors per hour under ideal conditions. It’s best seen from the Northern Hemisphere, and in 2026 the 34%-lit waxing crescent Moon shouldn’t interfere too much.
-
April 24 — Pi Puppids. This one is more of a wildcard: activity is variable, and the shower is best seen from the Southern Hemisphere. The First Quarter Moon will get in the way this year, so expectations should be kept modest — but if you’re lucky, the shower may still put on a small show.
Deep-sky objects in April 2026: galaxy season goes on
April brings an exciting galaxy season, perfect for observers armed with telescopes or binoculars. If you live in the Northern Hemisphere, look for the Leo Triplet — a trio of spiral galaxies (M65, M66, and NGC 3628, also known as the Hamburger Galaxy) nestled in the constellation of Leo. From our vantage point on the Earth, these galaxies appear tilted at different angles, giving them a unique appearance.
If you're in the Southern Hemisphere, point your binoculars at the Southern Pinwheel Galaxy in Hydra — one of the brightest nearby spiral galaxies visible to amateur observers. It's easy to see with binoculars, but use a small telescope to see its spiral structure.
But April has more to offer than just galaxies. Set your sights on M3, the first Messier object discovered by Charles Messier. This cluster contains about 500,000 stars and spans nearly half the size of the Moon's disk.

Other notable events in April 2026
- April 12 — International Day of Human Space Flight. This year, it also marks the 65th anniversary of Yuri Gagarin’s flight — the first time a human went to space. A nice excuse to revisit our article on the Anniversary of the First Human Space Flight.
- April 12 — 45 years since the launch of STS-1 / Columbia. Another anniversary for the same day! You can celebrate the shuttle’s launch together with Cosmonautics Day, and then celebrate its return on April 14, which marks 45 years since the landing of STS-1. Basically, a two-part space party.
- April 22 — Earth Day. We spend so much time looking up that it’s only fair to give some attention to the planet under our feet, too. Find out how to celebrate it properly in our article about Earth Day.
- April 24 — Hubble’s anniversary. On this day, the Hubble Space Telescope turns 36. A good moment to look back at one of the most famous space observatories ever launched — and maybe revisit our article about Hubble Space Telescope.
- April 24 — Space Day of China. China celebrates its national Space Day on the anniversary of the launch of Dong Fang Hong-1, the country’s first satellite. The date feels like a good excuse to take our quiz about Tiangong and see how much you really know about China’s space program.
- April 25 — Astronomy Day. A holiday for everyone who likes telescopes, dark skies, and saying “just one more look” at 2 a.m. If you’re in the mood to celebrate, start with our article about Astronomy Day — and maybe check whether your local observatory, planetarium, or astronomy club is hosting something nearby.
Celestial events in April 2026: frequently asked questions
What is the biggest celestial event in April 2026?
If we had to pick just one headline event of April 2026, it would probably be Comet C/2026 A1 (MAPS). It may become bright enough to see without optical aid, though its behavior near perihelion is still uncertain. Other strong contenders are Comet C/2025 R3 (PanSTARRS), the 4-planet alignment on April 18, and the April Lyrids later in the month.
Can I see a naked-eye comet in April 2026?
Possibly, yes. In April 2026, Comet C/2026 A1 (MAPS) and Comet C/2025 R3 (PanSTARRS) may both become visible without binoculars or a telescope. MAPS looks more impressive on paper, but it will stay close to the Sun and may not survive perihelion. PanSTARRS is a bit less dramatic, but also a bit more reliable.
Which planets are visible in April 2026?
All the major planets are around in April 2026, but not all of them are equally easy to see. Venus and Jupiter are the most comfortable targets in the evening sky, while Mercury, Mars, Saturn, and Neptune gather in the morning sky later in the month. Uranus is also visible after sunset, but for Uranus and Neptune, binoculars or a telescope will help a lot.
What is the best meteor shower in April 2026?
The April Lyrids are the best meteor shower of the month. They peak on April 22 and can produce up to 18 meteors per hour under good conditions. In 2026, the Moon won’t interfere too much, so the viewing conditions are reasonably good — especially in the Northern Hemisphere.
When is the best dark sky in April 2026?
The best dark-sky period in April 2026 is from April 14 to April 20, centered on the New Moon on April 17. This is the best time of the month to look for faint objects such as galaxies, star clusters, nebulae, and comets, when moonlight is least likely to get in the way.
How to navigate the night sky?
While navigating the night sky can be tricky, there is a useful tool for doing so — the Sky Tonight mobile app. Launch the app and point your device at the sky to learn what objects you are looking at. To find a specific celestial object, use the search feature in the app. We prepared some short video tutorials on how to use the app to its full potential.
Astronomical events in April 2026: bottom line
April 2026 is a good month to keep looking up. The sky brings the Lyrids, Mercury at its best, a small planet parade, and two comets — C/2026 A1 (MAPS) and C/2025 R3 (PanSTARRS) — that may become visible to the naked eye. Not bad for just one month.
If you want to know exactly when and where to look from your location, use the Sky Tonight app. It will show you what’s in the sky above you, help you find planets, stars, and comets, and save you from guessing which bright dot you’re staring at.
