Discovery of life in solid rock deep beneath sea may inspire new search for life on Mars
Newly discovered single-celled creatures living deep beneath the seafloor have provided clues about how to find life on Mars. These bacteria were discovered living in tiny cracks inside volcanic rocks after researchers perfected a new method cutting rocks into ultrathin slices to study under a microscope. Researchers estimate that the rock cracks are home to a community of bacteria as dense as that of the human gut, about 10 billion bacterial cells per cubic centimeter.

Hubble finds best evidence for elusive mid-sized black hole
Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as 'intermediate-mass,' which betrayed its existence by tearing apart a wayward star that passed too close.

On Mars or Earth, biohybrid can turn carbon dioxide into new products
Chemists have created a hybrid system of bacteria and nanowires that captures energy from sunlight and transfers it to the bacteria to turn carbon dioxide and water into organic molecules and oxygen. On Earth, such a biohybrid could remove carbon dioxide from the atmosphere. On Mars, it would provide colonists with raw material to manufacture organic compounds ranging from fuels to drugs. The efficiency is greater than the photosynthetic efficiency of most plants.

A Martian mash up: Meteorites tell story of Mars' water history
Researchers probed Martian meteorites to reconstruct Mars' chaotic history. Their findings suggest that Mars might not have had a global magma ocean.

ALMA resolves gas impacted by young jets from supermassive black hole
Astronomers obtained the first resolved image of disturbed gaseous clouds in a galaxy 11 billion light-years away by using the Atacama Large Millimeter/submillimeter Array (ALMA). The team found that the disruption is caused by young powerful jets ejected from a supermassive black hole residing at the center of the host galaxy. This result will cast light on the mystery of the evolutionary process of galaxies in the early Universe.

Paired with super telescopes, model Earths guide hunt for life
Astronomers have created five models representing key points from our planet's evolution, like chemical snapshots through Earth's own geologic epochs. The models will be spectral templates for astronomers to use in the approaching new era of powerful telescopes, and in the hunt for Earth-like planets in distant solar systems.

Looking for dark matter close to home
Eighty-five percent of the universe is composed of dark matter, but we don't know what, exactly, it is.

Astronomers use slime mould to map the universe's largest structures
The behaviour of one of nature's humblest creatures and archival data from the NASA/ESA Hubble Space Telescope are helping astronomers probe the largest structures in the Universe.

Star formation project maps nearby interstellar clouds
Astronomers have captured new, detailed maps of three nearby interstellar gas clouds containing regions of ongoing high-mass star formation. The results of this survey, called the Star Formation Project, will help improve our understanding of the star formation process.

Expanding universe: We may be in a vast bubble
The few thousand galaxies closest to us move in a vast 'bubble' that is 250 million light years in diameter, where the average density of matter is half as large as for the rest of the universe. This is the hypothesis put forward by a theoretical physicist to solve a conundrum that has been splitting the scientific community for a decade: at what speed is the universe expanding?

The strange orbits of 'Tatooine' planetary disks
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share very nearly the same plane, disks encircling wide binaries have orbital planes that are severely tilted. These systems can teach us about planet formation in complex environments.

New telescope design could capture distant celestial objects with unprecedented detail
Researchers have designed a new camera that could allow hypertelescopes to image multiple stars at once. The enhanced telescope design holds the potential to obtain extremely high-resolution images of objects outside our solar system, such as planets, pulsars, globular clusters and distant galaxies.

Precision mirrors poised to improve sensitivity of gravitational wave detectors
Deformable mirrors, which are used to shape and control laser light, have a surface made of tiny mirrors that can each be moved, or actuated, to change the overall shape of the mirror. S have, for the first time, made a deformable mirror based on the bimetallic effect in which a temperature change is used to achieve mechanical displacement.

On the origin of massive stars
A scene of stellar creation, captured by the NASA/ESA Hubble Space Telescope, sits near the outskirts of the famous Tarantula Nebula. This cloud of gas and dust, as well as the many young and massive stars surrounding it, is the perfect laboratory to study the origin of massive stars.

Scientists discover pulsating remains of a star in an eclipsing double star system
Scientists have discovered a pulsating ancient star in a double star system, which will allow them to access important information on the history of how stars like our Sun evolve and eventually die.

Mercury's scorching daytime heat may help it make its own ice at caps
Despite Mercury's 400-degree Celsius daytime heat, there is ice at its caps. And now a study shows how that Vulcan scorch probably helps the planet closest to the sun make some of that ice.

Exoplanet where it rains iron discovered
Researchers have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporize metals. Strong winds carry iron vapor to the cooler night side where it condenses into iron droplets.
