Supermassive black holes feed on cosmic jellyfish

An Italian-led team of astronomers used the MUSE (Multi-Unit Spectroscopic Explorer) instrument on the Very Large Telescope (VLT) at ESO's Paranal Observatory in Chile to study how gas can be stripped from galaxies. They ...

Image: Gaia's first full-colour all-sky map

While surveying the positions of over a billion stars, ESA's Gaia mission is also measuring their colour, a key diagnostic to study the physical properties of stars. A new image provides a preview of Gaia's first full-colour ...

Team redefines cosmic velocity web

The cosmic web—the distribution of matter on the largest scales in the universe—has usually been defined through the distribution of galaxies. Now, a new study by a team of astronomers from France, Israel and Hawaii demonstrates ...

Hubble displays a dwarf spiral galaxy

The subject of this NASA/ESA Hubble Space Telescope image is a dwarf galaxy named NGC 5949. Thanks to its proximity to Earth—it sits at a distance of around 44 million light-years from us, placing it within the Milky Way's ...

TRAPPIST-1 is older than our solar system

If we want to know more about whether life could survive on a planet outside our solar system, it's important to know the age of its star. Young stars have frequent releases of high-energy radiation called flares that can ...

An artificial eclipse for imaging extrasolar planets

In our hunt for Earth-like planets and extraterrestrial life, we've found thousands of exoplanets orbiting stars other than our sun. The caveat is that most of these planets have been detected using indirect methods. Similar ...

Magnetic fields in massive star formation cores

Studies of molecular clouds have revealed that star formation usually occurs in a two-step process. First, supersonic flows compress the clouds into dense filaments light-years long, after which gravity collapses the densest ...

Researchers brighten perspective of mysterious mini-halos

The largest gravitationally bound objects in the universe are galaxy clusters that form at the intersection of cosmic web filaments. These entities are shaped and grow through massive collisions as material streams into their ...

Cutting-edge Adaptive Optics Facility sees first light

The Unit Telescope 4 (Yepun) of ESO's Very Large Telescope (VLT) has now been transformed into a fully adaptive telescope. After more than a decade of planning, construction and testing, the new Adaptive Optics Facility (AOF) ...

Image: Intense star formation in the Westerhout 43 region

Hidden from our sight, the Westerhout 43 star-forming region is revealed in full glory in this far-infrared image from ESA's Herschel space observatory. This giant cloud, where a multitude of massive stars come to life in ...

The outer galaxy

The sun is located inside one of the spiral arms of the Milky Way galaxy, roughly two-thirds of the way from the galactic center to the outer regions. Because we are inside the galaxy, obscuration by dust and the confusion ...

Astronomers discover 'heavy metal' supernova rocking out

Many rock stars don't like to play by the rules, and a cosmic one is no exception. A team of astronomers has discovered that an extraordinarily bright supernova occurred in a surprising location. This "heavy metal" supernova ...

Possible first sighting of an exomoon

(Phys.org)—A team led by David Kipping of Columbia University has spotted what might be the first evidence of an exomoon. They have written a paper describing their findings and have uploaded it to the arXiv preprint server.
