Astronauts in orbit aboard ISS spent more than 7 hours on Saturday filling the new BEAM module with air. Check out this 25-second timelapse.
It’s “the first unambiguous detection of glycine at a comet” and supports the theory that the building blocks for life came to Earth from outer space.
What if if dark matter consisted of a population of black holes similar to those detected by LIGO last year? A new study analyzes this possibility.
Astrophysicists have taken a major step forward in understanding how these monster black holes are born.
The most detailed view of Pluto’s terrain you’ll see for a very long time, taken by the New Horizons spacecraft as it flew past Pluto on July 14, 2015.
Energy from our young sun – 4 billion years ago – helped create molecules in Earth’s atmosphere that allowed it to warm up enough to incubate life, says study.
On May 25, 1961, President John F. Kennedy gave a stirring speech to a joint session of Congress declaring his intention to land humans on the moon with a decade.
First total solar eclipse visible from the U.S. since 1991 (seen only from part of Hawaii), and first visible from contiguous U.S. since 1979. Start planning now!
Astronomers have found the first evidence of icy comets orbiting a sunlike star 160 light-years from Earth.
Here’s a collection of 10 unexpected, intriguing facts about the stars of our universe – including our sun – that you probably didn’t know!
The entire northern sky wheels around Polaris. Some assume it’s the brightest star in the sky. In fact, Polaris ranks only 50th in brightness.
Summertime star parties! We’ve added many new events to this list of astronomical events throughout the U.S. and Canada. Find one near you, join in and have fun.
A study suggests that 2 large meteorites hit Mars billions of years ago and triggered mega-tsunamis in Martian water oceans.
New research finds the ocean on Jupiter’s moon Europa could have the necessary balance of chemicals for life, even without active volcanoes.
The May 21 Blue Moon carries that name because it’s the 3rd of 4 full moons in a season. But can a season have just 2 full moons?
New Horizons imaged this distant Kuiper Belt Object twice. It has learned its location and spin, and dispelled a theory that 1994 JR1 is a quasi-satellite of Pluto.
An advanced computer simulation suggests that newly forming Earth-like worlds are likely to suffer a giant impact, like that thought to have created our moon.
Comet C/2013 X1 (PanSTARRS) is now visible in binoculars before dawn. This post has charts and other info that can help you spot the comet in the coming weeks!
We’re beginning to get questions about that red “star” in the east each evening. It’s Mars! We’ll pass between Mars and the sun this weekend.
The May 21 full moon is a seasonal Blue Moon – an older definition of the term. Watch for it this weekend, near brilliant Mars.
This galaxy – nicknamed ‘little lion’ – contains the lowest level of heavy elements ever detected in a gravitationally bound system of stars.
