"If this interaction between dark matter and neutrinos is confirmed, it would be a fundamental breakthrough."
A team using the NASA/ESA Hubble Space Telescope has uncovered a new type of astronomical object – a starless, gas-rich, dark-matter cloud that is considered a 'relic' or remnant of early galaxy formation. Nicknamed 'Cloud-9,' this is the first confirmed detection of such an object in the Universe.
Nearly every galaxy has a supermassive black hole in its core. Whether the black hole forms first and then the galaxy around it—or the other way around—is still a matter of some debate, but we know the evolution of both are deeply connected. We can use that relationship to study the black holes.
The shape of the universe is not something we often think about.

Media representatives joined French ESA astronaut Sophie Adenot, on Monday 5 January, for a hybrid press conference to learn more about her first mission to space.
Astronomers are gathering in Phoenix this week for the 247th meeting of the American Astronomical Society (AAS 247), where the latest discoveries from exoplanets, JWST and upcoming space missions will take center stage.
Regulus is the brightest star in the zodiacal constellation Leo.
The new findings strengthen the "RNA world" hypothesis that describes how the first life on Earth could have used RNA instead of DNA.
The Westerlund 2 star cluster is home to some of the Milky Way's brightest stars.
Many less massive galaxies appear to lack something astronomers thought was ubiquitous: a central, supermassive black hole.
So far, humanity has yet to find its first “exomoon” - a Moon orbiting a planet outside of the solar system. But that hasn’t been for lack of trying. According to a new paper by Thomas Winterhalder of the European Southern Observatory and his co-authors available as a pre-print on arXiv, the reason isn’t because those Moons don’t exist, but simply because we lack the technology to detect them. They propose a new “kilometric baseline interferometer” that can detect moons as small as the Earth up to 200 parsecs (652 light years) away.
January's full moon is often known as the 'Wolf Moon'.
Lunar landers from Blue Origin, Firefly Aerospace, Intuitive Machines and Astrobotic are gearing up for moon landing attempts in 2026 as the commercial exploration of deep space expands.
On 5 January 2026, the European Astronaut Centre (EAC) in Cologne, Germany, hosted a special tradition: the planting of an astronaut tree by ESA astronaut Sophie Adenot in honour of her first mission to space, εpsilon. This symbolic gesture celebrates her achievements and future mission while reinforcing the deep connection between space explorers and the planet they call home.
The X-Ray Imaging and Spectroscopy Mission (XRISM), a joint mission between the Japanese Aerospace Exploration Agency (JAXA) and NASA, launched on Sept. 7th, 2023. Its advanced imaging filters and spectrometers were designed to study black holes and neutron stars and detect the hot plasma in the intergalactic medium. Alongside the European Space Agency’s (ESA) X-ray Multi-Mirror Mission Newton (XMM-Newton) and NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), XRISM has provided the sharpest-ever X-ray spectrum of the iconic MCG–6-30-15.
A SpaceX Falcon 9 rocket carrying 29 Starlink satellites launched from Cape Canaveral Space Force Station in Florida on Sunday, Jan. 4, 2026.
Space debris falling to Earth is a growing threat to aircraft, and experts are trying to reduce the risk.
But as more and more satellites are launched into LEO...the region's getting a bit crowded.
NASA's ESCAPADE Mars probes embarked on a 'loiter' trajectory after launch, and scientists say that extra time in space could have some consequences for the twin spacecraft.
Earth is about to see three total solar eclipses in just under two years, with each successive path of totality moving west to east across the globe. Here's everything you need to know to plan an exquisite triple-header.
SpaceX launches the Starlink 6-88 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station on Jan. 4, 2026. This was the company’s first Starlink mission of the year and the first Falcon 9 launch from the Eastern Range of 2026. Image: Michael Cain/Spaceflight Now
Update Jan. 4, 3:38 a.m. EST (0838 UTC): SpaceX confirms deployment of the 29 Starlink satellites.
