An epic outburst from a baby star still in the process of forming has been captured in a spectacular Hubble image. Roughly 1,250 light-years away, in the Orion molecular cloud star-forming region, jets from a protostar are punching through the cloud at supersonic speeds, heating the gas and causing it to glow brightly. The result … Read more
The smallest known main-sequence star in the Milky Way galaxy is a real pixie of a thing. It’s called EBLM J0555-57Ab, a red dwarf 600 light-years away. With a mean radius of around 59,000 kilometers, it’s just a smidge bigger than Saturn. That makes it the tiniest known star to support hydrogen fusion in its core, … Read more
Screens brighten with the flow of words. Perhaps they are emails, hastily scrawled on smart devices, or emoji-laden messages exchanged between friends or families. On this same river of the digital, millions flock to binge their favorite television programming, to stream pornography, or enter the sprawling worlds of massively multiplayer online roleplaying games, or simply … Read more
The Bernardinelli-Bernstein comet, identified in 2021, is officially the biggest comet ever observed. The new record, reported on the preprint website arXiv and now accepted for publication in the journal Astronomy and Astrophysics Letters, bumps the Hale-Bopp comet from the top spot. Hale-Bopp was discovered in 1995 and became visible to the naked eye in 1996; it … Read more
Sometimes astronomers and astrophysicists are working at such gigantic, mind-bending scales – in terms of both distance and time – that you can’t help but be awestruck at the new discoveries they keep coming out with. Case in point: a temperature check of the Universe in its youngest phase, just 880 million years after … Read more
One day in June 1195, around noon, something unusual took place near the city of London. A dark cloud appeared to give birth to a white orb of light, which dropped towards the Thames river, rising and falling in a spinning motion. The observation – recorded by the Benedictine monk Gervase of Christ Church … Read more
If you are outside doing some stargazing in the Western Hemisphere this evening and are looking up at just the right time, you might catch sight of something that will appear quite strange: a small circular cloud of light that will rapidly expand to roughly the apparent size of a full moon, before finally fading … Read more
A new image of the Flame Nebula shows the interstellar cloud as we’ve never seen it before. A team of astronomers using the Atacama Pathfinder Experiment (APEX) telescope has captured the star-forming region in radio wavelengths, revealing details that we had never seen before. The Flame Nebula, which is close to the famous Horsehead … Read more
A computer simulation tracks 9 million years of evolution within a stellar nursery – also known as a giant molecular cloud – in which stars are born Space 11 January 2022 By Chen Ly The most detailed simulations to date of giant molecular clouds (GMCs) hint that we may need to rethink our understanding of … Read more
Stretching thousands of light-years across the Milky Way, a newly discovered filament of hydrogen named Maggie is one of the biggest structures ever discovered in our galaxy, and researchers think there could be others like it. A group of astronomers led by researchers at the Max Planck Institute of Astronomy (MPIA) in Germany has spotted … Read more
