The 5 biggest discoveries from the hunt for gravitational waves

Wed, 10/18/2017 - 5:48pm
Detecting gravitational waves has given us a new way to observe the universe by listening to ripples in space-time. Here are five of the biggest finds from LIGO

Gravitational waves have let us see huge neutron stars colliding

Wed, 10/18/2017 - 1:00pm
We’ve taken the first pictures of neutron stars colliding 130 million light years away. The resulting gravitational waves may solve some big cosmic mysteries

Hiding in plain sight: The mystery of the sun’s missing matter

Wed, 10/18/2017 - 8:00am
A mass equivalent to 1500 Earths has vanished from the sun. Tracking it down could transform how we see the stars

A tech-destroying solar flare could hit Earth within 100 years

Wed, 10/18/2017 - 6:30am
If the sun spews “superflares” as often as other stars, one could take down power systems, damage the ozone layer and destroy satellites in the next century

Astronaut wee could show us how the plumes on Enceladus work

Tue, 10/17/2017 - 7:07pm
The way spaceships vent urine and water may be a good stand-in for studying how jets of vapour escape the hidden ocean on one of Saturn’s icy moons

A gaggle of 7 moons keep Saturn’s rings from breaking apart

Tue, 10/17/2017 - 3:08pm
The gravity from seven of its moons stops Saturn’s bright outer ring from spreading out and dispersing into space, according to Cassini spacecraft measurements

We can finally map the spiral arm on the far side of the galaxy

Thu, 10/12/2017 - 3:00pm
Using a jet of radio waves, astronomers have begun to map the other side of the Milky Way. Within 10 years we could have a complete map of the entire galaxy

Distant dwarf planet near Pluto has a ring that no one expected

Wed, 10/11/2017 - 2:00pm
The tiny world Haumea has a ring, the most distant we’ve found in our solar system. This may mean rings encircle other far-off worlds in the solar system

Giant black hole seen flickering on and off after galaxy snack

Wed, 10/11/2017 - 9:10am
Active Galactic Nuclei occur when a black hole devours a cloud of gas and dust and shines really brightly. Now one has been seen doing it twice

It was always crazy to shoot for Mars before colonising the moon

Tue, 10/10/2017 - 11:25am
Common sense is prevailing in human space exploration, and the moon is back as the place we need to colonise before a riskier trip to Mars, says Paul Marks

Half the universe’s missing matter has just been finally found

Tue, 10/10/2017 - 6:18am
About half the normal matter in our universe had never been observed – until now. Two teams have finally seen it by combining millions of faint images into one

Lunar volcanoes and lava lakes gave the early moon an atmosphere

Fri, 10/06/2017 - 1:16pm
The same volcanic eruptions that made the dark patches we can see on the moon spewed out enough hot gas to create an atmosphere billions of years ago

The sun’s energy could speed up dark matter so we can detect it

Thu, 10/05/2017 - 11:37am
If dark matter is made of ultra-light particles with very little energy, one way to find them is to catch them after they ricochet off the sun

Methane burps on young Mars helped it keep its liquid water

Mon, 10/02/2017 - 12:00pm
The mystery of how water on Mars lasted for millions of years may come down to methane explosions that warmed the planet enough to melt ice and make rivers flow
