Chile's Paranal Observatory Saved from Industrial Development

28-01-2026 22:33 via universetoday.com

After months of protests led by Nobel laureate Reinhard Genzel, the American energy company AES Andes has abandoned plans to build a massive solar and wind facility just kilometres from one of the world's premier telescope sites. The decision preserves the pristine night skies above Chile's Paranal Observatory, where the European Southern Observatory operates some of humanity's most powerful eyes on the universe.

Solving the Century Old Puzzle of Our Galaxy's Neighborhood

28-01-2026 22:28 via universetoday.com

Nearly a century after Edwin Hubble discovered the universe's expansion, astronomers have finally explained the nagging mystery of why most nearby galaxies rush away from us as if the Milky Way's gravity doesn't exist? The answer lies in a vast, flat sheet of dark matter stretching tens of millions of light years around us, with empty voids above and below that make the expansion appear smoother than it should.

Mercury May Not Be "Dead" After All

28-01-2026 22:16 via universetoday.com

Researchers using machine learning have discovered hundreds of mysterious bright streaks on Mercury's surface that appear to be caused by gases escaping from the planet's interior. The finding suggests the Solar System's smallest planet isn't the static, geologically dead world we thought it was, Mercury might still be active today, continuously releasing material into space even billions of years after its formation.

Do Dwarf Galaxies Merge In The Milky Way's Halo?

28-01-2026 20:48 via universetoday.com

Our current understanding of the Cosmos shows that structures emerge hierarchically. First there are dark matter densities, then dwarf galaxies. Those dwarfs then merge to form more massive galaxies, which merge together into even larger galaxies. Evidence of dwarf galaxy mergers is difficult to obtain, but new research found some in the Milky Way's halo.

De wilde jeugd van planeten vastgelegd op beeld

28-01-2026 17:00 via scientias.nl

Voor het eerst hebben astronomen een gedetailleerde blik geworpen op de turbulente ’tienerjaren’ van planetenstelsels. Nieuwe, zeer gedetailleerde opnamen van 26 stofringen rond andere sterren laten zien hoe jonge planeten hun omgeving herschikken. Astronomen hebben met de Atacama Large Millimeter/submillimeter Array, kortweg ‘ALMA’ een uniek familiealbum samengesteld. Het toont niet de geboorte van planeten, maar […]

Meer is duidelijk over waar de jet van het superzware zwarte gat van M87 precies begint

28-01-2026 14:57 via astroblogs.nl

Sommige sterrenstelsels stoten krachtige stromen geladen deeltjes – jets of straalstromen – vanuit hun centrum de ruimte in. De prominente jet van Messier 87 (M87) in het sterrenbeeld Maagd is zichtbaar over afstanden van 3.000 lichtjaar en kan worden waargenomen over het volledige elektromagnetische spectrum. Deze jet wordt aangedreven door de centrale motor, het superzware […]

The Magnetic "Birdsong" of the Smallest Planet

28-01-2026 12:58 via universetoday.com

BepiColombo is slowly uncovering more and more fun facts about Mercury as it continues its preliminary mission. One of the more interesting things found so far is a magnetic “chorus” that appears similar to a phenomenon found in Earth’s much larger magnetic field. A new paper in Nature Communications from the researchers responsible for the probe’s Mio instrument that is studying Mercury’s magnetic field describes what could be thought of as a form of magnetic birds

AI onthult honderden kosmische afwijkingen in het Hubble-archief

28-01-2026 11:14 via astroblogs.nl

Een team van sterrenkundigen heeft een geavanceerde, door kunstmatige intelligentie (AI) ondersteunde techniek gebruikt om zeldzame astronomische verschijnselen te ontdekken in gearchiveerde gegevens van de Hubble ruimtetelescoop. Het team analyseerde bijna 100 miljoen uitsneden van afbeeldingen uit het Hubble Legacy Archive, elk met een afmeting van slechts enkele tientallen pixels (7 tot 8 boogseconden). In […]

Biofilms May Have Sparked Life on Earth—and Could Sustain It in Space

28-01-2026 06:01 via universetoday.com

It's 2041 and an astronaut on Mars Station 1 orbiting the Red Planet is inspecting life support systems in the bowels of the habitat. They open a compartment and are aghast to discover a mysterious goop clinging to the walls in microgravity that definitely shouldn't be there. In their shock, they immediately have flashbacks from every alien-based science fiction movie they've ever seen, and are convinced they not only just discovered the first signs of alien life, but they won't live to tell abo

The "China Sky Eye" Traces Fast Radio Bursts to a Binary Star System

Intermittent Black Hole Jets Are Like A 'Cosmic Volcano'

28-01-2026 00:04 via universetoday.com

Supermassive black holes grow larger by accreting matter. When they're actively accreting matter they're called active galactic nuclei (AGN). AGN are the most luminous sources of persistent radiation in the Universe, yet they turn on and off as the SMBH passes through quiet and active phases. Astronomers have found one that is just turning on its powerful jets after a long period of dormancy.
