The planet is so close to its host star that it only has a 5.36 day-long orbit. At this distance, surface temperatures should hover around 428 Kelvin (155 °C; 311 °F).
We've learned so much about Mars, but pressing questions still remain.
The solar system is very different from our own.
A brave star and a supermassive black hole confirm Einstein's theory of general relativity.
This is good news.
Finally, the Orion capsule is now complete and ready for tests involving humans slated in 2023.
The new study explains why our galaxy doesn't travel with the expansion of the universe.
The map is amazing.
Who's 'we' though?
It doesn't necessarily have to be red wine...
It's one of the fundamental universal features -- and we're still struggling to understand it.
Scientists envision using a very thin material to build a huge greenhouse on Mars.
A group of researchers at NASA is preparing for the final steps to launch the Española chile pepper into space in November.
Researchers plan to employ them as producers of food, antibiotics, other materials for astronauts on deep space missions.
Could this be the key to ensuring that the ISS lives long and prosper?
Titan is of interest because it is the only body in our solar system (besides Earth) that has liquid rivers, lakes, and seas on its surface.
Gamma-ray particles trillions of times more energetic than regular light hit the Tibetan plateau.
Uranus' rings are thin and imperceptible to all but the largest telescopes.
That's pretty metal.
The early universe was a wild place to be in.
Interstellar travel requires some impossible physics.
It was 'imported' from space via a meteorite impact.
The temperature around the sun is millions of times hotter than the sun's surface itself.
It was tens of thousands of times more massive than the ones our Sun puts out.
Talk about a surprising find!
It's a wild theory -- but is it crazy enough to work?
It's an unexpected side effect of a useful plan.
It's so close that it shouldn't be able to retain an atmosphere. And yet it does.
Comets seem to release molecular oxygen all the time -- and some scientists have recreated the process on Earth.
A mysterious and alarming uptick in dangerous chlorine-based chemicals has been tracked down to eastern China.
Can't the Moon just go to the tap like the rest of us?
Comfortably insulated.
A hybrid bio-technology could pave the way for future space missions.
Clumps of dark matter might be shooting through the Milky Way's stars.
The tech that brought humans to the moon also made its way into our homes.
The original timeline was pushed forward four years by the Trump Administration -- and now NASA needs the bucks to make it happen.
The moon may be tectonically active, according to groundbreaking new research.
They were much brighter than they were supposed to be.
Don't panic -- this is just a drill.
The mystery of Earth's water may have been solved by a team of Japanese researchers.
During a blood moon, a brief flash of light caught astronomers' attention.
Finally, a theory that explains how the moon formed that isn't too over the top.
Which means we might need new physics to explain the observation.
Auroras are dazzling to behold, but also a nuisance for the aerospace industry.
Duck and cover!
The blast might help scientists answer fundamental questions about the solar system's formation.
"Hey, I can see my house from here!"
Take a walk on the dark side -- of the moon.
The Mars InSight lander has sensed a quake within the planet.
This is a real victory for little projects.
