Measles is not a disease to take lightly—but it is also very preventable with vaccines

Ciaran Martin, the former head of cyber security at GCHQ, says the UK government was "naive" to expect a request for Apple to weaken its encryption services to remain secret. He thinks governments must come to terms with the fact that uncrackable encryption is here to stay.

As ESA’s Hera planetary defence mission flew past planet Mars it autonomously locked onto dozens of impact craters and other prominent surface features to track them over time, in a full-scale test of the self-driving technology that the spacecraft will employ to navigate around its target asteroids.

Uncorrected errors in science and the unconscionable reluctance to correct them erodes trust in science, throws away taxpayer money, harms the public’s health and can kill innocent people

Researchers have found an environmentally safer way to extract the lithium 6 needed to create fuel for nuclear fusion reactors. The new approach doesn’t require toxic mercury, as conventional methods do

A riotous photography collection from a recent underwater mission off the coast of Chile shows new and fascinating deep-sea creatures—including a “mystery mollusk,” a bioluminescent jellyfish and a “sea pig”

In the ongoing debate over the benefits and harms of smartphone use in children, initial data from a US survey suggests the devices can actually improve well-being and social connections, but social media use may be more harmful

Breathtaking photos of this month's total lunar eclipse capture a blood red moon and star-studded Milky Way over NOIRLab's Cerro Tololo Inter-American Observatory in Chile.

A strange blue spiral lit up the sky over Europe on Monday night (March 24), with residents of the UK and other countries speculating on its true nature on social media.

Experts are already looking into the risks of piracy in space and solutions to this potentially devastating economic and legal problem.

When it comes to safe places for life, supermassive black holes are probably the last place you'd consider safe for nearby planets, let alone life-bearing ones. There are good reasons for this: those monsters at the hearts of galaxies suck down everything that comes into contact with them. When they do that, they blast out killer radiation. Neither activity is necessarily good for life. Or is it? As it turns out, radiation from these active galactic nuclei (AGN) can nurture life under the right circumstances.

There is no sea on Earth large enough to contain the Shark nebula.

Scientists have detected a fascinating spiral galaxy located about one billion light-years away. At the heart of this cosmic goliath, powerful radio jets are blasting out of its centre, stretching six million light years into space. A team of researchers have suggested that a smaller dwarf galaxy plunged into its centre, passing close to its supermassive black hole triggering immense flares, intense radiation and driving the colossal radio jets. Surprisingly however, despite the tremendous amounts of energy, the galaxy has kept its spiral structure.

China’s Chang’e-6 mission has been exploring the largest crater on the Moon. It’s known as Aitken Basin and is found at the South Pole of the Moon where craters are permanently shadowed. The crater is a whopping 2,500 km across and measures 10km deep and Chang’e-6 data has revealed that a giant asteroid smashed into the Moon about 4.25 billion years ago.

A cosmic coincidence has led to one of the most amazing images ever captured by NASA’s James Webb Space Telescope.

The detection of bird flu in a sheep is another sign that the H5N1 virus is adapting to hop to new hosts

Here's where to be to catch rare views of the cusps of the sun appearing in the east at sunrise during the partial solar eclipse on March 29, 2025.
