Observations of R Doradus, a nearby red giant, provide the first timescale for convection on the surface of any star other than the Sun.
Low-orbit Earth could become inoperable for spacecraft and satellites if this complacency persists, with dire consequences.
New data suggests our galaxy may reside in an immense basin of gravitational attraction far larger than Laniākea.
Young galaxies such as this should have been "small and messy looking."
How could we feed astronauts on lengthy space missions? These researchers have a quirky idea.

The closest single star to our solar system reveals a planet with a three-day year.
We may be on the cusp of finally breaking the standard model of cosmology.
The ESA's probe found life on Earth. No comment on its intelligence.
"Freya Castle" is unlike any rock seen before on the Red Planet.
As outlandish as it sounds, using X-rays from a nuclear bomb is backed by solid scientific evidence.
Talk about a giant in the universe.
2024 PT5 will be a temporary visitor, arriving in September and flying off again in November.
This is the closest pair detected in the local universe using multiwavelength (visible and X-ray light) observations.
They're not actual spiders, of course, but rather strange geological features.
For the past few years, a series of controversies have rocked the well-established field of cosmology. In a nutshell, the predictions of the standard model of the universe appear to be at odds with some recent observations. There are heated debates about whether these observations are biased, or whether the cosmological model, which predicts the […]

The collision shows just how wild the Solar System can be.
While space is mostly empty, it does have some matter and particles spread throughout it.
The idea that aliens may have visited the Earth is becoming increasingly popular. Around a fifth of UK citizens believe Earth has been visited by extraterrestrials, and an estimated 7% believe that they have seen a UFO. The figures are even higher in the US – and rising. The number of people who believe UFO […]

The Great Red Spot we see today is not nearly as old as once thought -- and it might soon disappear.
For years, scientists have speculated about the nature of water on exoplanets, especially on super-Earths and sub-Neptunes — planets larger than Earth but smaller than Neptune. The prevailing view has been that these distant worlds could be covered by vast oceans, potentially making them prime candidates for hosting life. However, a groundbreaking study published in […]
Amorphous materials, which are rarely studied on Earth, yield insights into the history of Gale Crater and the early Martian environment.
