In this photo released on April 14, 2025, NASA’s James Webb Space Telescope revealed the gas and dust ejected by a dying star at the heart of NGC 1514. Using mid-infrared data showed the “fuzzy” clumps arranged in tangled patterns, and a network of clearer holes close to the central stars shows where faster material punched through.

This scene has been forming for at least 4,000 years — and will continue to change over many more millennia. At the center are two stars that appear as one in Webb’s observation, and are set off with brilliant diffraction spikes. The stars follow a tight, elongated nine-year orbit and are draped in an arc of dust represented in orange.

One of these stars, which used to be several times more massive than our Sun, took the lead role in producing this scene. “As it evolved, it puffed up, throwing off layers of gas and dust in in a very slow, dense stellar wind,” said David Jones, a senior scientist at the Institute of Astrophysics on the Canary Islands, who proved there is a binary star system at the center in 2017.

Astronomers modeled how black holes merge and found that most converged black holes started as large stars in a binary system. They also found evidence of triple and quadruple black holes!

Young people are struggling with mental health and relationships, but there are small shifts in beliefs and behaviors that could help.

Between 1985 and 1989, a warming of 0.06 C per decade was observed, while from 2019 to 2023, the sea-surface temperature rose by 0.27 C per decade. This suggests that sea surface temperatures are rising 4.5 times faster since 2019 than they were at the end of the 1980s.

The study calculated monthly global mean sea-surface temperature using global satellite data records generated through ESA’s Climate Change Initiative (CCI). The dataset used observations from 20 infrared radiometers on board satellites including ESA’s ERS-1, ERS-2, Envisat, Copernicus Sentinel-3 and two microwave radiometers from 1980 to 2023 to provide a globally accurate temperature trend.

By slashing teams that gather critical data, the administration has left the federal government with no way of understanding if policies are working — and created a black hole of information whose consequences could ripple out for decades.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered evidence that suggests the presence of a long-sought supermassive black hole at the heart of the nearby spiral galaxy Messier 83 (M83). This surprising finding, made possible by Webb’s Mid-Infrared Instrument (MIRI), reveals highly ionised neon gas that could be a telltale signature of an active galactic nucleus (AGN), a growing black hole at the center of a galaxy.

Metformin, a widely used and affordable diabetes drug, could prevent a form of acute myeloid leukaemia in people at high risk of the disease, a study in mice has suggested. Further research in clinical trials will be needed to confirm this works for patients.

Scientists have hypothesized since the 1960s that the Sun is a source of ingredients that form water on the Moon. When a stream of charged particles known as the solar wind smashes into the lunar surface, the idea goes, it triggers a chemical reaction that could make water molecules.

Now, in the most realistic lab simulation of this process yet, NASA-led researchers have confirmed this prediction.
