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.
A bizarre new state of matter known as a time crystal seems to suspend the laws of thermodynamics almost indefinitely, two new experiments suggest.

When measuring time, we normally assume that clocks do not affect space and time, and that time can be measured with infinite accuracy at nearby points in space. However, combining quantum mechanics and Einstein’s theory of general relativity theoretical physicists from the University of Vienna and the Austrian Academy of Sciences have demonstrated a fundamental limitation for our ability to measure time.
A new paper uncovers a number of coincidences suggesting that recently discovered radio bursts are consistent with advanced civilizations using light sails for transportation.

The earliest supermassive black holes may have been big to start with. If so, it would help explain the recent detection of such beasts within a billion years of the big bang.
Supermassive black holes take a long time to build, so we expect to see only a few in the early universe. The more of them we find, the less likely it is that they all grew the way most modern black holes do, by devouring dust and gas.
Everybody gets a moon! With the discovery of a small moon orbiting the third-largest dwarf planet, all the large objects that orbit beyond Neptune now have satellites.
Trans-Neptunian objects (TNOs) spend most or all of their orbits beyond Neptune. Last April, the dwarf planet Makemake became the ninth of the ten TNOs with diameters near or above 1,000 kilometres known to have a moon.
When it comes to human health and spaceflight, there are a lot of concerns as NASA casts its eye toward deep space. Among the more familiar problems are muscle and bone mass loss due to the lack of gravity. But more recently, scientists have grown increasingly concerned about astronauts returning to Earth with blurred vision, flattened eyeballs, and inflamed optic nerves after long-duration missions.
Training in Antarctica or on the International Space Station won’t provide adequate preparation for human settlement on Mars, according to new research.
Bigelow Aerospace’s founder believes we could have lunar depots by 2020 if the Trump administration prioritizes the funding and national urgency the project would require.
With Bigelow Aerospace, SpaceX, and Blue Origin at the forefront of the private space industry, space tourism may one day soon be a regular part of life on Earth.
Mars may have been a wetter place than previously thought, according to research on simulated Martian meteorites conducted, in part, at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
Based in Lima, Peru, the International Potato Center (CIP) is dedicated to collecting and altering potato varieties found around the world. The CIP began as an effort to alleviate global hunger by introducing special strains of the hardy vegetable to places with arid soils and harsh environments.
