There could be planets out there which are even more habitable than Earth
When searching for potentially habitable exoplanets, scientists are forced to take the low-hanging fruit approach. Since Earth is the only planet we know of that...
Scientists find an extrasolar moon with active volcanoes
A rocky extrasolar moon (exomoon) with bubbling lava may orbit a planet 550 light-years away from us. This is suggested by an international team of...
Scientists assemble a fingerprint for Earth
The fingerprint could help find habitable planets beyond the Solar System. Astronomers have assembled a "fingerprint" for Earth, which could be used to identify a...
Scientists find a golden glow from a distant stellar collision
On August 17, 2017, scientists made history with the first direct observation of a merger between two neutron stars. It was the first cosmic event...
Scientists discover a giant planet swinging around its star on a bizarre path
Astronomers have discovered a planet three times the mass of Jupiter that travels on a long, egg-shaped path around its star. If this planet were...
Dark sides of some hot exoplanets have clouds made of minerals and rocks
A new study by McGill University astronomers has found that the temperature on the nightsides of different hot Jupiters is surprisingly uniform. This suggests the...
What’s Mars solar conjunction, and why does it matter?
The daily chatter between antennas here on Earth and those on NASA spacecraft at Mars is about to get much quieter for a few...
Why we need to get back to Venus
Just next door, cosmologically speaking, is a planet almost exactly like Earth. It’s about the same size, is made of about the same stuff and...
Salt deposits on Mars hold clues to sources of ancient water
For centuries, miners have burrowed into the earth in search of salt—laid down in thick layers from ancient oceans long since evaporated. When scientists saw...
Scientists discover a giant planet around 2,800 times the mass of earth
Astronomers have discovered a new planet around a nearby star that is nine times the mass of Jupiter and more than 2,800 times the...
