Gravitational Lenses Deliver a Verdict on the Hubble Tension
The Hubble Tension is one of the great mysteries of cosmology. Solving it might require a fundamental change in how we understand the universe - but scientists have to prove it actually exists first. A new paper from a collective of cosmologist researchers known as the TDCOSMO Collaboration adds further fuel to that first with updated measurements of the “Late Universe” measurement of the Hubble Constant using gravitational lenses of quasars, which shows that the Tension might exist after all.
Satellite constellations could obscure most space telescope observations by late 2030s: 'That part of the image will be forever lost'
"The natural question that comes up is: how many more space telescopes will be affected when all these constellations are launched?"
This Week's Sky at a Glance, December 12 – 21
Big Jupiter now rises in the east-southeast less than an hour after dark. It's high in sharp telescopic viewing by about 10 p.m.
Earth from Space: Pariacaca Mountain Range, Peru
Image: Following International Mountain Day, which creates awareness of the importance of mountain environments around the world, the Copernicus Sentinel-2 mission takes us over the Pariacaca Mountain Range in Peru.
Lake-Star Analog for Europa’s Manannán Spider
What geological features on Earth can be used to better understand unique geological features on Jupiter’s icy moon, Europa? This is what a recent study published in *The Planetary Science Journal* hopes to address as a team of researchers investigated potential Earth analogs for studying a unique geological feature on Europa scientists identified almost 30 years ago. This study has the potential help scientists gain insights into Europa’s unique geological features, some of which scientists hypothesize are caused by the moon’s internal liquid water ocean.
Blue Origin targeting Dec. 18 for historic 1st spaceflight of wheelchair user
Blue Origin is targeting Dec. 18 for its NS-37 suborbital launch, which will fly a wheelchair user to space for the first time ever.
SpaceX launches Starlink satellites from Florida on worldwide 300th orbital flight of 2025 (video)
A SpaceX Falcon 9 rocket carrying 29 Starlink satellites launched from Cape Canaveral Space Force Station in Florida on Dec. 11, 2025. It was the 300th worldwide orbital launch attempt of 2025.
NASA's Chandra telescope uses 'X-arithmetic' to reveal how black holes shape galaxy clusters (images)
A novel "X-arithmetic" technique reveals how black holes shape the universe's largest structures.
Did Life Begin in Prebiotic Surface Gels?
How did life begin on Earth? Based on studies of fossilized bacteria, scientists theorize that life first emerged on Earth over 4 billion years ago as simple, single-celled organisms. Over time, these organisms evolved to incorporate photosynthesis and sexual reproduction, eventually giving rise to more complex multicellular organisms, plants, and, eventually, mammals. Despite this scientific consensus, the question of how inorganic chemicals came together to form organic molecules that gradually evolved into self-replicating systems remains unclear.
Astronomers capture close-up images of nova explosions on 2 dead stars in unprecedented detail
The nova eruptions come about when a white dwarf steals too much matter from a close red giant companion.
Webb’s First Look at TRAPPIST-1e Hints at a Titan-like Atmosphere
Observations from the James Webb Space Telescope suggest the planet might have a nitrogen-and-methane atmosphere — but more data are needed to rule out a bare rock scenario.
SpaceX plans to go public in 2026, seeks $1.5 trillion valuation: reports
SpaceX plans to go public in 2026 and will seek a valuation of $1.5 trillion, according to media reports.
A New Five-Year Survey Of The Magellanic Clouds Will Answer Some Questions About Our Neighbours
The Large and Small Magellanic Clouds are irregular dwarf galaxies and satellites of the Milky Way. The LMC is about 163,000 light-years away and the SMC is about 206,000 light-years away, and their close proximity makes them excellent laboratories for the study of galaxies in general. The Clouds are the focus of a new research group being formed at the Leibniz Institute for Astrophysics Potsdam (AIP).
57 ways to capture a dying star: Astronomers get a glimpse of what will happen when our sun dies
"With ALMA, we can now see the atmosphere of a dying star with a level of clarity in a similar way to what we do for the sun."
Astronomers discover images of rare Tatooine-like exoplanet with a strange 300-year orbit: 'Exactly how it works is still uncertain'
The planet formed 50 million years after the dinosaurs died, making it incredibly young in cosmic terms.
Two Stars’ Swept by the Solar System 4.5 million Years Ago
Two winter stars left their mark long ago on wispy gas clouds near the solar system. Their passage might even have influenced life on Earth.
AI helps pilot free-flying robot around the International Space Station for 1st time ever
"This is the first time AI has been used to help control a robot on the ISS."
James Webb Space Telescope finds strongest evidence yet for atmosphere around rocky exoplanet: 'It's really like a wet lava ball'
Astronomers have found the strongest evidence yet of an atmosphere around a rocky exoplanet.
Scientists map of old Mars river basins for the 1st time. These could be great places to search for ancient life
"We did the simplest thing that could be done — we just mapped them and pieced them together."
