Sterrenkundigen ontdekken een gloednieuw type astrofysisch object: een zwart gat ster

14-08-2026 10:52 via astroblogs.nl

Sterrenkundigen van MIT en andere instellingen hebben een extreem heldere rode stip in het vroege heelal ontdekt. Het object lijkt op een enorme ster, zo groot als ons zonnestelsel. Maar het straalt ook 100 miljard keer meer energie uit dan welke bekende ster dan ook fysiek kan produceren. Sterker nog, zulke energieën komen dichter in […]

The Rooms We Build To Survive In, And The Ones We Build To Live In

14-08-2026 00:09 via universetoday.com

What does a home actually need to do for us, beyond keeping the weather out? Engineers at MIT have started mapping the answer for astronauts heading to the Moon and Mars, tracing exactly how the walls, layouts and lighting around a person shape their stress, their loneliness and their sense of belonging. It turns out the science of surviving a place and the science of living in one are not the same thing at all, and I have spent enough of the last year thinking about that difference to know how

The Ingredients For Planets Turned Up Astonishingly Early

13-08-2026 23:56 via universetoday.com

Planet building was supposed to be one of the universe's slow projects, something that only got going billions of years after the Big Bang. New research suggests otherwise. The raw materials for rocky worlds, and perhaps even the water needed for life, may have been ready to go just 100 million years after the Big Bang, long before the first galaxies had even taken shape.

A Massive Stream of Gas Tilted This Planet-Forming Disk

13-08-2026 20:51 via universetoday.com

Astronomers found evidence that a giant stream of gas flowing into the GW Orionis young triple-star system may have tilted its planet-forming disk, offering a new explanation for why some planetary systems are misaligned. The next step is to search for shock fronts in the system, and to search for more of these massive streams of gas in other systems.

NASA Wants to Float Microscopic 'Tracers' on Sunlight to Map the Edge of Space

13-08-2026 17:15 via universetoday.com

The atmospheric is a dynamic place, and just how well we understand that dynamism depends on what part of the atmosphere it is. Low altitudes can be reached by traditional balloons, with full suites of sensing equipment. Higher reaches are the domain of satellites, with their zippy orbits allowing them to travel through the less dense regions. But there a section scientists call the “ignorosphere”, between 30-100 kilometers up that still plays a major role in global climate dynamics,

Amazing Views of Wednesday's Total Solar Eclipse

13-08-2026 16:45 via universetoday.com

It was an eclipse for the ages. This past week, many an eclipse chaser and the ‘eclipse curious’ made the journey to stand in the shadow of the Moon, for the only total solar eclipse of 2026. Viewers across northeastern Spain had thrilling views of a low to the horizon eclipse at sunset, while viewers to the north and across Iceland had dicier, cloudy skies to contend with. Here are amazing reader views of the eclipse, along with a few special ones from space.

Two Million X-Ray Sources, and One Cluster That Doesn't Fit

13-08-2026 00:52 via universetoday.com

The eROSITA telescope has released its second great catalogue of the X-ray sky with close to two million sources across half the sky, roughly double what it published before. Buried in it is a result from Bonn that matters more than the headline number. A team there went after the faintest part of a massive galaxy cluster, the outer region where fresh material is still arriving along threads of gas stretching between clusters. Nobody had measured that emission before. The gas turns out to be hot

Twenty Years of Watching One Galaxy, and It Made Less Sense

13-08-2026 00:20 via universetoday.com

Blazars are galaxies with a jet aimed almost directly at us, and they flicker across every part of the spectrum at once. Almost everything we think we know about them comes from short observing campaigns just a handful of days, every year or two, in one narrow band of energy. A Polish and German team has now done the opposite, following a single blazar for nearly twenty years with two orbiting observatories and in two observations from 2012 they found something in the spectrum that nobody had pr

Nine Hundred Telescopes and One Chance a Year

13-08-2026 00:03 via universetoday.com

Reading the atmosphere of another world means catching starlight as it filters through that planet's air during a transit. The signal is about one part in a million and a true Earth twin transits only once a year, so you cannot simply repeat the measurement until the noise averages away. Each attempt has to work on its own. A team led from Shanghai has proposed the alternative to building an impossibly large mirror in space - nine hundred, one metre telescopes, flying together, watching the same

Solar Magnetic Field Braids May Have a Previously Hidden Cause

12-08-2026 15:35 via universetoday.com

Scientists using the Daniel K. Inouye Solar Telescope (DKIST) in Hawai'i have found a mechanism occurring on the Sun's surface that they think is heating our star's outer atmosphere. The process, called a Kelvin-Helmholtz Instability (KHI), could well be the root cause of a phenomenon called flux braiding that builds up and moves around on the Sun and heats the coronasphere. This discovery may well also explain the fundamental physics of similar activity at other stars.

How to Find Lunar Ice? Moonquakes to the Rescue!

12-08-2026 00:55 via universetoday.com

The surface of the Moon is a bleak and forbidding place that might be hiding a lot of water ice on and under the dusty landscape. However, most possible ice deposits don't just stand out in an image. You need specialized mapping to find traces of water ice. So, scientists have devised another way to find the Moon's frosty hidden reserves. They use seismic waves from moonquakes as locator beacons.

Every Snowflake Needs a Speck of Dust and So Do Planets

11-08-2026 23:33 via universetoday.com

A snowflake cannot form out of nothing. Water vapour will sit in the air quite happily, supercooled and reluctant, until it finds a speck of dust to build on and then it crystallises around it. Cosmochemists have had a version of that problem for decades. The early Solar System was a furnace of gas, and the first solid grains had to condense out of it somehow, yet condensing from a perfectly uniform gas is slow and difficult work. New research from Caltech, analysing fragments of a meteorite tha

The Dark Matter Detector in the Scottish Borders

Hunting for dark matter usually means building something enormous and burying it — a tank of liquid xenon in a mine, a magnet the size of a lorry, decades of engineering and a great deal of money. A team in Japan have just done it differently. They realised that the Earth's own magnetic field is larger than any magnet we could ever construct, and that the gap between the ground and the ionosphere behaves as a natural resonating cavity, ringing at around eight cycles per second. If dark mat

What If There's a Star Inside a Black Hole?

11-08-2026 23:03 via universetoday.com

Ask what lies inside a black hole and the honest answer has always been a bit of a shrug and something about a singularity, a point where density becomes infinite and physics stops being able to tell you anything at all. It is the most unsatisfying answer in astrophysics, second only perhaps to what happened before the Big Bang. Now two theorists in China have produced a solution in which something else sits inside the horizon entirely, a neutron star, whole and intact, twelve kilometres across,

Watching the First Moments in a Star's Death

Astronomers were fortunate when the Einstein Probe detected the difficult-to-observe initial shock break out (SBO) from a supernova. The SBO is the first electromagnetic indication that a star is going to explode, and by observing it and the aftermath, researchers were able to determine what type of progenitor star exploded, and what it's pre-explosion environment was like.

The ESCAPE Mission Will Study the Evolution of Exoplanet Atmospheres

11-08-2026 18:05 via universetoday.com

Exoplanets need to be habitable for a long time for complex life to develop. To sustain habitability, exoplanets need to retain their atmospheres. But many exoplanets are exposed to extreme ultraviolet light and coronal mass ejections that can strip atmospheres away. A new mission aims to understand these processes and help exoplanet scientists identify exoplanets that can stay habitable for meaningful lengths of time.

Robots Could Build Massive Metamaterial Radars in Orbit

Tracking the debris orbiting at high velocity in space is only going to get harder over time. We have ground-based radar systems, such as the Space Fence, designed to detect pieces down to around 10 cm. But finding objects smaller than that, which can still cause a lot of damage traveling at 17,000 miles per hour, requires completely new thinking. One potential solution is a new idea from Dr. David Smith of Duke University, who was recently funded for a NASA Innovative Advanced Concepts (NIAC) P

NASA Funds 'Interworld Slingshot' Concept to Map Solar System Resources

In-situ Resource Utilization (ISRU) is going to be a critical technical component of any human expansion out into the solar system. Our first challenge with utilizing those resources, though, is finding them. We know how, at least in theory - send a probe to an asteroid, or a particular part of the Moon, and take a sample, maybe analyze that sample with some spectrographs, or send it back to Earth to be poked and prodded. The problem with this methodology is simple - it’s expensive. Sendin
