After decades of planning and building, the world's largest digital camera at the heart of the Vera C. Rubin Observatory on the summit of Cerro Pachón in Chile has snapped its first imagery – from test observations spanning a 10-hour window.
-
A new collaborative project dubbed the COSMOS-Web field has compiled the most comprehensive cosmic map ever, including images of the early universe as far back as 13.5 billion years.

If you've been wondering how long the day on Uranus is, you probably need to get out more. But if you have, you'll be interested to know that observations by the Hubble Space Telescope have shown that it's 28 seconds longer than previously thought.

Finding alien life won’t be a flying saucer landing at the White House – NASA scientists will hold a press conference to excitedly show off a chart that’s incomprehensible to most people. Now we’re a step closer to that boring but groundbreaking day.

Astronomers have detected mysterious X-ray signals coming from a nearby white dwarf star for more than 40 years. We may now know where they’re coming from – the death throes of a planet being torn to shreds and raining down on the star.
-
Astrophysicists have done a bit of crime scene investigation. They’ve traced radioactive elements on the seafloor back to the cosmic explosions they might have come from – and potentially linked the event to evolutionary changes in viruses in Africa.

After a couple of successful Kickstarters for versions of its book-sized smart telescope, DwarfLab opted to jump straight into production for the Dwarf III. We've recently been out stargazing and wildlife watching with this budget-friendly sky watcher.

Asteroid 2024 YR4 has grabbed headlines lately, after NASA briefly gave it had the highest ever chance of an impact for an asteroid of hazardous size. Thankfully, new observations have dropped that probability to almost zero – for Earth, anyway.
-
Astronomers have discovered an exoplanet with a tail, like a gigantic comet. The planet, known as WASP-69b, is slowly evaporating in the radiation of its host star.

To find black holes we usually have to look thousands of light-years away. But a new study suggests we could find evidence of them right here on Earth, as tiny tunnels they’ve carved out in rocks or old buildings.
-
Astrophysicists have detected the most energetic electrons ever recorded raining down on Earth. With trillions of times the energy of visible light, these cosmic rays seem to be coming from a powerful source relatively close to our solar system.

Astronomers have clocked a cosmic collision at 3.2 million km/h (2 million mph). A new instrument has spotted a galaxy crashing through a group of others at incredible speeds, creating a shock wave that’s changing the region completely.
