From April through June, Leo the Lion — one of the zodiacal constellations — is a prominent fixture in the evening sky. It’s quite easy to spot.
You'll see Leo the Lion in the sky in 2 parts: the backwards question mark pattern represents Leo's head, and the triangle at the back represents the Lion's hindquarters. The bright star Regulus
is part of the backwards question mark pattern, which is known as The Sickle. Image via Derekscope
Whether the raindrop is made of water on Earth, methane on Titan, or liquid iron on an alien world, a new study shows that all raindrops will fall to the ground at a similar size.

From central North America on April 12, 2021, the moon will be less than 24 hours old. On April 12 at sunset, as soon as the sun slips below the horizon, the race begins to spot a young moon, less than a day old … before it sets!
Small asteroid 2021 GW4 will pass extremely close to Earth on Monday, April 12, 2021. It’ll pass just 12,313 miles (19,816 km) from Earth’s surface, or about 5% the Earth-moon distance.

New images of the oldest known pairs of quasars, farthest and oldest yet seen, show that their home galaxies are colliding.
This artist's concept shows 2 blazingly bright quasars and the merging galaxies in which they reside. Both quasars have supermassive black holes at their cores. A new study suggests that, as the 2 galaxies merge and the quasars get closer together, the 2 black holes will merge to form an even-more-massive black hole. Image via NASA

In 2021, the likely peak morning for the Lyrids is Thursday morning, April 22. But the mornings around that date might be good, too. The moon is waxing – staying out longer after dark each night – so you’ll want to watch the time of moonset carefully.

The long-sought “lost golden city” of Aten has been found near Luxor, Egypt, in the Valley of Kings. “The mission expects to uncover untouched tombs filled with treasures,” the scientists said.

Beta Centauri isn’t as famous as Alpha Centauri, but together, these brilliant Southern Hemisphere stars have inspired legends and guided mariners.
In this image taken at the European Southern Observatory’s La Silla Observatory in Chile, the Southern Cross is clearly visible, with the yellowish star, closest to the dome, marking the top of the cross. Drawing a line downward through the crossbar stars takes you to the bluish star, Beta Centauri, and then to the yellowish Alpha Centauri. Image via ESO / Wikimedia Commons
Astronomers detected a new, nearby, repeating fast radio burst, originating from a spot near the great spiral galaxy M81.
