Primordial Black Holes Can Trigger Type Ia Supernovae, and Astronomers Should be Able to Find Them

30-07-2026 21:22 via universetoday.com

Primordial black holes (PBH) remain hypothetical, but that isn't stopping astrophysicists from figuring out how they could interact with other stellar objects. New research shows how PBHs, formed in the early Universe from collapsing pockets of dense subatomic matter instead of from stars, can enter white dwarfs. In some cases, that could've triggered a Type Ia supernova with particular chemical fingerprints, which should be detectable.

Radio Array Detects Polarized Light From a GRB

30-07-2026 20:57 via universetoday.com

On March 10, 2026, the Fermi telescope gamma-ray burst team reported the detection of a long-duration gamma ray burst that occurred when a star exploded inside a dense, highly magnetized cloud of hydrogen gas. That HII region is a bubble of ionized hydrogen created by winds from a massive young star. Astronomers immediately turned as many telescopes as possible to view the burst and its afterglow, including the NSF's Karl Jansky Very Large Array.

The ELT's Spectrograph Could Sniff Out Biosignatures on Other Worlds

30-07-2026 17:40 via universetoday.com

Before any major telescope commissioning, there are dozens of papers that attempt to define what we can expect from it. We’re starting to see some come through for the Extremely Large Telescope (ELT), which hopefully will get a more imaginative name when the 39m behemoth is officially commissioned in Chile in the 2030s. A new paper from Evann Kurzawa-Ferrandez and his co-authors at NASA’s Jet Propulsion Laboratory, and available in pre-print on arXiv, showcases what kind of biologica

Nederland sluit zich als waarnemer aan bij het Cherenkov Telescope Array Observatory

30-07-2026 16:16 via astroblogs.nl

Op 20 juli is Nederland officieel als waarnemer toegetreden tot het CTAO ERIC (Cherenkov Telescope Array Observatory, European Research Infrastructure Consortium). De toelating versterkt de samenwerking tussen de Nederlandse wetenschappers in dit deelgebied van de sterrenkunde en ’s werelds grootse observatorium voor gammastraling. Het observatorium wordt nu ondersteund door elf landen en één intergouvernementele organisatie. […]

De kosten voor het lanceren van raketten zijn sinds 1960 met 96% gedaald!

30-07-2026 16:04 via spacepage.be

Uit een nieuw onderzoek blijkt dat de kosten van ruimtelanceringen de afgelopen zes decennia met 96% zijn gedaald en dat ze tegen 2040 mogelijk met bijna evenveel zullen dalen. Een dergelijke verbetering zou echter kunnen worden belemmerd door een aantal uitdagingen, zoals de toename van ruimtepuin in een baan om de aarde of het feit dat één enkel bedrijf de commerciële ruimtelanceringen zou monopoliseren, voegden de onderzoekers eraan toe.

The Exciting Plan to Photograph an Alien Continent

30-07-2026 13:18 via universetoday.com

NASA has selected a concept study, led by physicist Paul Stankus, exploring whether a pair of spacecraft flying in tight formation could one day produce an actual image of an Earth like exoplanet's surface, oceans, continents and all. It's an early stage idea, backed by NASA's Innovative Advanced Concepts program, but if it ever came together, it would represent an extraordinary leap beyond simply detecting a distant world to genuinely seeing its face.

A Thermal Camera Trick Could Let LIGO See Twice as Far

30-07-2026 13:10 via universetoday.com

A team of researchers have found a surprisingly simple way to boost the sensitivity of gravitational wave detectors like LIGO. It’s surprisingly simple to, just point an ordinary thermal imaging camera at the mirrors themselves. The technique could improve LIGO's next upgrade by up to 31%, letting it detect neutron star collisions tens of millions of light years farther away, and is already being built into the design of its planned successor, Cosmic Explorer.

Mars' Double Storm Problem

30-07-2026 13:03 via universetoday.com

A new study presented at the Royal Astronomical Society's National Astronomy Meeting suggests that solar storms may warm the Martian lower atmosphere, but only when they strike during a major Martian dust storm. The discovery was accidental, emerging from a search for a different effect entirely, and hints that the weather system on Mars may be more tangled and interconnected than scientists previously assumed.

De explosie van een zwart gat bereikt een afstand van maar liefst 300.000 lichtjaar

30-07-2026 10:50 via astroblogs.nl

Een team van onderzoekers heeft ontdekt dat de winden die door superzware zwarte gaten worden gegenereerd, 100 keer krachtiger zijn dan eerder werd gedacht. Ze transporteren energie over afstanden van ongeveer 300.000 lichtjaar. De ontdekking toont aan dat deze explosieve winden een enorme impact hebben op de uitgestrekte ruimte buiten de sterrenstelsels waarin ze zich […]

Alien Signals May Hide in Unexplored High Radio Frequencies

30-07-2026 07:12 via universetoday.com

Confirming the existence of extraterrestrial intelligence via radio signals, also called technosignatures, is the cornerstone of radio astronomy. While humanity has been asking since time immemorial whether or not we’re alone in the universe, radio astronomers are at the frontlines trying to tirelessly answer this longstanding question. To accomplish this, they’ve traditionally focused on a specific radio frequency band called the “water hole”, which resides between 1.42

NASA's reddingsmissie moet nu zelf gered worden

30-07-2026 06:55 via spacepage.be

Het verloopt niet zo soepel voor de nieuwste satellietreddingsmissie van NASA. NASA lanceerde op 3 juli de Swift Boost-missie, waarbij een gespecialiseerd ruimtevaartuig naar een lage baan om de aarde werd gestuurd tijdens de laatste vlucht van de vanuit de lucht gelanceerde Pegasus XL-raket van Northrop Grumman.

Quantum Physics Could Help Us Find Earth 2.0

30-07-2026 04:56 via universetoday.com

When astronomers talk about directly imaging an exoplanet that is orbiting a far away star, the analogy they most commonly go with is trying to spot a fireflight next to a massive search light. An Earth-like exoplanet is incredibly dim - usually between 100 million and 10 billion times fainter than its host star. Understandably, that makes them very difficult to see. But a new paper from Hyunsoo Choi of Hanyang University in South Korea and his co-authors, which is available in pre-print on arXi
