To find a planet, look for the signatures of planet formation
Finding forming planets is a tough but important job for astronomers: Only three planets have ever been discovered caught in the process of forming, and the most recent of these was found just weeks ago. Study: Gemini-LIGHTS: Herbig Ae/Be and massive T-Tauri protoplanetary disks imaged with Gemini Planet Imager Evan Rich , a postdoctoral researcher at the University of Michigan, suggests that instead of looking for individual planets forming, astronomers might have better luck looking for the likely environments in which they form.

No signs (yet) of life on Venus
No signs (yet) of life on Venus
The unusual behaviour of sulphur in Venus- atmosphere cannot be explained by an -aerial- form of extra-terrestrial life, according to a new study. Even if -our- Venus is dead, it-s possible that Venus-like planets in other systems could host life Paul Rimmer Researchers from the University of Cambridge used a combination of biochemistry and atmospheric chemistry to test the -life in the clouds- hypothesis, which astronomers have speculated about for decades, and found that life cannot explain the composition of the Venusian atmosphere.

Gaia mission sees strange stars in most detailed Milky Way survey to date
Gaia mission sees strange stars in most detailed Milky Way survey to date
The ESA Gaia mission has released its new treasure trove of data about our home galaxy. Astronomers - including Professor Conny Aerts from KU Leuven - describe strange 'starquakes', stellar DNA, asymmetric motions and other fascinating insights in this most detailed Milky Way survey to date. Gaia is ESA's mission to create the most accurate and complete multi-dimensional map of the Milky Way.

What faint dwarf galaxies can tell astronomers about galaxy formation
Here we sit, situated on Earth amid the Milky Way galaxy. And here the Milky Way galaxy sits, having grown inside a large dark matter halo Dark matter is a curious thing: It doesn't interact with light, so it should really be called transparent matter, says Eric Bell , professor of astronomy at the University of Michigan.

Largest chemical map of the Milky Way unveiled
Largest chemical map of the Milky Way unveiled
The European Space Agency's Gaia mission involving UCL researchers has released a new treasure trove of data about our home galaxy, including the largest chemical map ever produced and the full 3D motions of 35 million stars. Gaia is ESA's mission to create the most accurate and complete multi-dimensional map of the Milky Way.

A look back in time to the origins of our solar system
A look back in time to the origins of our solar system
Researchers from the University of Göttingen analyse a rock from the asteroid Ryugu Researchers from the University of Göttingen are among the first in the world to have analysed rock samples from the asteroid Ryugu. Asteroids are remnants from the very beginnings of our solar system and, at around 4.6 billion years old, are about as old as the solar system itself.

Astronomers may have detected a 'dark' free-floating black hole
Astronomers may have detected a ’dark’ free-floating black hole
If, as astronomers believe, the death of large stars leave behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy. The problem is, isolated black holes are invisible. Now, a team led by University of California, Berkeley, astronomers has for the first time discovered what may be a free-floating black hole by observing the brightening of a more distant star as its light was distorted by the object's strong gravitational field - so-called gravitational microlensing.

New clues suggest how hot Jupiters form
New clues suggest how hot Jupiters form
Johns Hopkins astronomers discover new way of determining the relative age of exoplanets and prove there are multiple ways these planets form Since the first hot Jupiter was discovered in 1995, astronomers have been trying to figure out how the searing-hot exoplanets formed and arrived in their extreme orbits.

Ground-breaking number of brown dwarfs discovered
Ground-breaking number of brown dwarfs discovered
Brown dwarfs, mysterious objects that straddle the line between stars and planets, are essential to our understanding of both stellar and planetary populations. However, only 40 brown dwarfs could be imaged around stars in almost three decades of searches. An international team led by researchers from the Open University and the University of Bern directly imaged a remarkable four new brown dwarfs thanks to a new innovative search method.

It was true detective work!
It was true detective work!
The InSight mission on Mars is running out of power and most of its functions could be shut down in the months to come. Some have already been deactivated. However, the attached seismometer, SEIS, will remain in operation for as long as possible. ETH Professor Domenico Giardini takes stock of three years of marsquake measurements.

New Sky Map Showing 4.4 Million Galaxies
New Sky Map Showing 4.4 Million Galaxies
For 7 years, an international research team that included the Hamburg Observatory of Universität Hamburg gathered data for a new sky map depicting 4.4 million galaxies. Previously, these galaxies were unknown. The map has now been published in the journal "Astronomy & Astrophysics". This discovery was possible by the largest-ever radio telescope LOFAR (Low Frequency Array), which has receiving stations in 7 European countries.

Hubble Space Telescope captures largest near-infrared image to find universe's rarest galaxies
Hubble Space Telescope captures largest near-infrared image to find universe’s rarest galaxies
An international team of scientists recently released the largest near-infrared image ever taken by NASA's Hubble Space Telescope, enabling astronomers to map the star-forming regions of the universe and learn how the earliest, most distant galaxies originated. Named 3D-DASH, this high-resolution survey will allow researchers to find rare objects and targets for follow-up observations with the recently launched James Webb Space Telescope (JWST) during its decades-long mission.

Detecting new particles around black holes with gravitational waves
Detecting new particles around black holes with gravitational waves
Clouds of ultralight particles can form around rotating black holes. A team of physicists from the University of Amsterdam and Harvard University now show that these clouds would leave a characteristic imprint on the gravitational waves emitted by binary black holes. Black holes are generally thought to swallow all forms of matter and energy surrounding them.

Scientists explain why Uranus and Neptune are different colours
Scientists explain why Uranus and Neptune are different colours
Layers of haze particles are responsible for the different blue hues of the ice giants Neptune and Uranus. Neptune and Uranus have much in common - they have similar masses, sizes, and atmospheric compositions - yet Neptune looks distinctly bluer than its planetary neighbour Uranus. New research led by Professor Patrick Irwin, Department of Physics , University of Oxford suggests that a layer of haze that exists on both planets is behind the different hues of blue.
