Two heads are better than one in the latest images from NASA’s James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. Nebula PMR 1 is a cloud […]

An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to investigate molecular gas in a nearby galaxy known as NGC 1387. Results of the observational campaign, published Feb. 3 in Monthly […]

Astronomers have captured the central region of our Milky Way in a striking new image, unveiling a complex network of filaments of cosmic gas in unprecedented detail. Obtained with the Atacama Large Millimeter/submillimeter Array (ALMA), […]

A team of scientists from around the world has created the first system that can predict when and where extremely powerful solar storms, called superflares, are most likely to happen. These storms can disrupt power […]

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These methods are internally consistent and […]

One of the largest known stars in the universe underwent a dramatic transformation in 2014, new research shows, and may be preparing to explode. A study led by Gonzalo Muñoz-Sanchez at the National Observatory of […]

Indian astronomers have investigated an ultraluminous X-ray pulsar in the galaxy NGC 4631, designated X-8. The new study, described in a paper published Feb. 16 on the arXiv preprint server, provides essential information regarding the […]

Every winter, thousands of tourists travel to high-latitude regions like Scandinavia, Canada, and Alaska hoping to see the Aurora Borealis or Northern Lights. Vincent Ledvina, an aurora guide and Ph.D. student in space physics at […]

How did the construction of the Subaru Telescope transform Japanese astronomy? A new study provides a quantitative answer by analyzing scientific publications and their citation impact during the telescope’s early years. Drawing on large-scale publication […]

For the first time, a much younger version of the sun has been caught red-handed blowing bubbles in the galaxy by astronomers using NASA’s Chandra X-ray Observatory. The bubble—called an “astrosphere”—completely surrounds the juvenile star. […]
