Stephen Hawking is going to go to space. The cosmologist and physicist will leave the Earth on board Richard Branson’s spaceship, he has said.
Professor Hawking told Good Morning Britain that he’d never dreamed he’d be able to head into space. But “Richard Branson has offered me a seat on Virgin Galactic, and I said yes immediately”, he said.
The Large Hadron Collider has discovered new sub-atomic particles that could help to explain how the centres of atoms are held together.
The particles are all different forms of the so-called Omega-c baryon, whose existence was confirmed in 1994.
The distant past. A long time ago. Right now. Right here. With the way we speak about time and space highlighting their deep parallels, is it any wonder science keeps uncovering new similarities between the two?
Time is weird – in spite of what we think, the Universe doesn’t have a master clock to run by, making it possible for us to experience time differently depending on how we’re moving or how much gravity is pulling on us.

Dust to dust. The mysterious dark flows on Mars may not be water after all. Instead, they could be rivulets of sand, set in motion by sunlight on the Martian surface.
The dark streaks form on Mars’s slopes during warm seasons, and are known as recurring slope lineae. While there is no direct evidence of water near these areas, the leading theory is that they are caused by briny water streaming down the sides of craters and hills.
It’s possible that Mars had rings at one point and may have them again someday. That’s the theory put forth by Purdue University scientists have developed a model that suggests that debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago and alternates between becoming a planetary ring and clumping up to form a moon.
Over the past decade, the international Cassini mission has revealed intense activity at the southern pole of Saturn’s icy moon, Enceladus, with warm fractures venting water-rich jets that hint at an underground sea. A new study, based on microwave observations of this region, shows that the moon is warmer than expected just a few metres below its icy surface.
From all this, it can be concluded that roughly three and a half billion years ago, the mouth of the Kasei Valles region still had water on its surface – possibly still in liquid form but most likely in the form of ice. Volcanic activity – which Mars was still experiencing at the time – then triggered the release of flood waters, which created debris and erosion features throughout the region.

Both chambers of Congress just passed the NASA Authorization Act of 2017. With this transformative development, the space agency got a lot more than just $19.508 billion in funding. They also got a very clear mandate: Get humanity to Mars.
The hellishly hot planet fries spacecraft electronics, so NASA scientists devised a machine inspired by ancient technology
The odds of life spreading between the worlds of the newly-discovered seven-planet TRAPPIST-1 system are up to 1,000 times greater than in our own solar system. That’s the conclusion of a new analysis posted March 2 to the arXiv, an online repository of scientific papers.
On the dwarf planet Ceres, volcanoes rage — but instead of hot lava coming out of them as on Earth, they spew brine and ice.

The discovery of young stars in old star clusters could send scientists back to the drawing board for one of the Universe’s most common objects.
Dr Bi-Qing For, from the International Centre for Radio Astronomy Research in Perth, said our understanding of how stars evolve is a cornerstone of astronomical science.
Asteroids may not hit our planet at regular intervals after all. Scientists have reached this conclusion after analyzing impact craters formed in the last 500 million years, concentrating on precisely dated events.
A recently discovered “asteroid pair” is the youngest such duo known in Earth’s solar system, and it appears to have sprouted twin comet-like tails, new observations reveal.

A prototype space-based gravitational wave detector performed far better than expected during its trial run, raising prospects that a follow-on observatory to listen for echoes from the biggest crashes in the cosmos will be launched ahead of schedule.
Time travel is possible, in a way. Astrophysicists are about to make the sci-fi fantasy a reality using a giant infrared telescope that can peer at star formations 13 billion light years away, seeing them just like they were that many years ago, and illuminating the recipe for the soup that is the universe.
