A spacecraft set to launch this year will throw a spotlight on the mysterious ‘dark side’ of the universe.
Not all lunar eclipses are alike. An astronomer explains the science behind the slight dimming of the Moon on May 5, 2023.
Artificial intelligence tools are making waves in almost every aspect of life, and astronomy is no different. An astronomer explains the history and future of AI in understanding the universe.
The most energetic events in the universe shower us with unbelievably energetic particles of light. Capturing these can help us to solve some enticing cosmic mysteries.
Machine learning is becoming an indispensable tool in astronomy by sorting through enormous datasets from telescopes.
Astronomers have long known where water is first formed in the universe and how it ends up on planets, asteroids and comets. A recent discovery has finally answered what happens in between.
With the help of thousands of citizen scientists, a new study measured exactly how much brighter night skies are getting every year.
With more than 100 lunar missions planned in coming years, space junk near the Moon could become an issue for humanity. No agency tracks lunar space junk, so two astronomers decided to do it themselves.
NASA released five new images from the James Webb Space Telescope, revealing incredible details of ancient galaxies, stars and the presence of water in the atmosphere of a distant planet.
It has taken eight months to test and calibrate all of the instruments and modes of the James Webb Space Telescope. A scientist on the team explains what it took to get Webb up and running.
This year, two groups of astronomers plan to send messages containing information about humans and the location of Earth toward parts of space they think may be home to intelligent life.
The astronomy and astrophysics decadal survey for the 2020s lays out plans to search for life on distant planets, understand the formation of galaxies and solve deep mysteries of physics.
Hypervelocity stars were discovered only 15 years ago and are the closest things in existence to real shooting stars. They travel at millions of miles per hour, so fast that they can escape from galaxies.
Tracing the cosmic origin of toothpaste, scientists got a glimpse into the surprising chemistry of early galaxies.
Such a mission could be developed soon, allowing astrophysicists to take selfies of the solar system and use the Sun’s gravity as a lens to peer deep into space.
Astronomers know a lot about what’s in outer space – and think it’s possible it never ends.
In the early morning of May 26, 2021, there will be a super blood-red lunar eclipse. The show will be spectacular and can all be explained by the orbits of the Earth and Moon.
