NASA's WISE mission has a dramatic view of the universe based on more than a decade of research, gazing into the deep sky with infrared vision.
Comets are remnants from the early days of the solar system, billions of years ago. Primarily made of ice and dust, these "dirty snowballs" orbit the sun and in habit the Oort cloud, an area in the outskirts of the solar system beyond Pluto. As comets approach the inner solar system, solar wind from the sun can sweep dust back into a long tail. When these comets are close enough to Earth, they can appear as dazzling objects in the night sky. Space probes from Earth have visited several comets to learn more about their composition. Learn more about comets, icy wanderers in the solar system.
Five years after spotting 'Oumuamua, the first known object from beyond our solar system passing through, scientists are still figuring out what the strange object says about planetary systems.
The peak of the Draconid meteor shower, which appears to originate from the constellation Draco, will sadly be outshined by the full Hunter's Moon.
The October Camelopardalids are somewhat mysterious in that astronomers aren't quite sure what their origin is.
Astronomers know of only a few dozen examples of these active asteroids, but they suspect more are out there — and you can join the hunt.
A 'disconnection event' in the bright Comet Leonard caught the eyes of judges at Royal Observatory Greenwich.
'The End Is Nye' shows The Science Guy coming back from disasters to save the world (again). It is streaming on Peacock now.
Cosmic impacts can make planets and moons more porous than previously thought, potentially boosting their ability to host life, a new study finds.
Comet 67P/Churyumov-Gerasimenko is richer in organic molecules than scientists thought, which could have implications for how life on Earth began.
Debris from the most spectacular comet outburst ever is visible from Earth this month and astronomers hope the observations might shed light on the puzzling event that brightened up the sky in 2007.
Donald Edward Machholz was an American amateur astronomer who was the leading visual comet discoverer, credited with the visual discovery of 12 comets that bear his name.
Stargazers around the world captured some dazzling views of the Perseid meteor shower as it peaked overnight Friday and Saturday (Aug. 12-13)
The Perseid meteor shower reaches its peak overnight on Aug. 12 and 13, unfortunately coinciding with this month’s full Sturgeon Moon.
The peak of the annual Perseid meteor shower shares the sky with August's full moon this week, meaning it will be difficult to view the iconic shooting stars.
Debris produced by the most spectacular comet outburst ever observed will be visible from Earth later this month even to amateur telescopes. Here is how to look for it.
The peak shooting star season has arrived with six meteor showers expected to pepper Earth in the upcoming weeks as the planet hurtles through fields of cometary debris.
Mysterious comet K2 made its closest approach to Earth yesterday and is continuing its journey toward the sun.
One of the farthest active comets ever spotted will makes closest approach to Earth on July 14, and here's how you can catch the action live.
K2, the most pristine comet ever observed, makes a visit to Earth this week. Here is what scientists have learned about it since its surprising discovery.
As a huge comet makes its closest approach to Earth on July 13, you might be curious why it's so hard to spot.
