The moon and Mars make a close approach and will be in conjunction on Tuesday, April 25. The pair will be visible to the unaided eye in the right conditions.

The SuperBIT telescope recently flew to the edge of the atmosphere on a football field-sized balloon. Its first images may start to unveil the true nature of dark matter.

The Lyrid meteor shower peaks overnight on Saturday (April 22), offering skywatchers the opportunity to spot some fast and bright meteors as they streak through the night sky.

Artificial intelligence experts have been challenged to join astronomers in the hunt for planets outside the solar system as part of the Ariel Data Challenge 2023, launched on April 14.

NASA's LUCY asteroid-hopping mission has for the first time spotted four of its asteroid targets which it will visit from 2027 onwards and send those images back to Earth.

The new moon occurs just after midnight on Thursday (April 20), ahead of the end of the holy month of Ramadan for Muslims across the globe, while also signaling the end of a rare type of eclipse.

A rare hybrid eclipse sweeps across the surface of Earth on April 20, appearing as a total eclipse, annular eclipse or transitioning between both, depending on one's vantage point.

Amateur astronomers have taken images of Europe's Jupiter explorer JUICE as it commenced its journey to the largest planet of the solar system.

The mapping of matter in the cosmos helps to confirm Einstein's theory of general relativity and reveals more about mysterious dark matter.

The James Webb Space Telescope has observed the earliest and most distant galaxies ever spotted by humanity. But why do some of them look so strange and distorted?

The JUICE spacecraft has captured stunning space "selfies" as it departs Earth and embarks on its eight-year voyage to Jupiter.

Scientists have found that the distribution of matter in galactic clusters supports the lambda cold dark matter model of cosmology.

International Dark Sky Week 2023 runs from Saturday, April 15 and Saturday, April 22 to ensure that policymakers aren’t in the dark about the problem of light pollution and its effects.

The James Webb Space Telescope has spotted galaxies further away in the universe than any other instrument before. How can we be sure these early galaxies aren't closer and more recent?

Mini solar flares created in the lab could improve our understanding of coronal loops and the high-energy emissions from the sun that can threaten communication and power systems on Earth.

Skywatchers will get the opportunity to take a good look at the galaxy Messier 51 with its incredible whirlpool shape when it rises high in the sky over Earth on Friday, April 14.

Astronomers have questioned whether the sun fits in with its family of stars. New research finally settles the debate.

A machine learning algorithm has sharpened the first-ever image of a black hole, the supermassive monster at the heart of the galaxy Messier 87, to its maximum fidelity.

Things could be heating up for a newly discovered warm Jupiter planet. The exoplanet planet around 1,000 light years away could snuggle up to its star but only if another planet plays matchmaker.

The JUICE mission will begin its trek to the gas giant Jupiter on Thursday, April 13. When will it arrive, and what will it discover about the solar system's largest planet and its icy ocean moons?

An extreme ice age that left the planet in a state called "Snowball Earth" around 650 million years ago may have actually allowed some liquid oceans to survive and harbor life.

Mercury will reach its highest point in the sky tonight (April 11), but it'll still be a challenge to observe.

A new simulation showing millions of galaxies demonstrates how the Nancy Grace Roman space telescope will turn back the clock for astronomers and help them investigate lingering cosmic mysteries.

New guidelines from governments and the space sector include "rules of the road" that could help reduce risky collisions between space junk and spacecraft.

Europe's JUICE mission will launch on Thursday (April 13), but won't reach Jupiter until 2031. Why will it take so long?
