Astronomers peer inside the ‘Dragon Cloud’
arXiv (2023). DOI: 10.48550/arxiv.2303.15499″> The inner core of the “dragon cloud” complex. Credit: Barnes et al, arXiv (2023). DOI: 10.48550/arxiv.2303.15499 How did the most massive stars form? Astronomers have debated…
The first black hole portrait got sharper thanks to machine learning
If the first image of a black hole looked like a fuzzy doughnut, this one is a thin onion ring. Using a machine learning technique, scientists have sharpened the portrait…
New findings that map the universe’s cosmic growth support Einstein’s theory of gravity
A new image reveals the most detailed map of dark matter distributed across a quarter of the entire sky, reaching deep into the cosmos. The findings, from the Atacama Cosmology…
Webb Reveals Never-Before-Seen Details in Cassiopeia A
The explosion of a star is a dramatic event, but the remains the star leaves behind can be even more dramatic. A new mid-infrared image from NASA’s James Webb Space…
Twinkling stars fuel interstellar dust
Of the many kinds of stars, asymptotic giant branch (AGB) stars, usually slightly larger and older than our own sun, are known to produce interstellar dust. Dusty AGBs are particularly…
The Smithsonian’s ‘Lights Out’ inspires visitors to save the fading night sky
Bright, artificial lights are drowning out the night sky’s natural glow. Now, an exhibition is highlighting some of the consequences of a fading starry night — and how people can…
How to see the invisible: Using the dark matter distribution to test our cosmological model
How do you measure dark matter, which by definition emits no light? Watch how it impacts things you can see — specifically, how light from distant galaxies bends around it, as predicted…
Scientists Unveil a 5.7 Terapixel Global Image of Mars
A planet-spanning online image of Mars created at a scale of 5 meters per pixel was unveiled today. The image is freely available to the public and can be accessed…
Scientists find first evidence that black holes are the source of dark energy
NGC524: NGC 524 is a lenticular galaxy in the constellation Pisces. It is at a distance of about 90 million light-years away from Earth. Credit: ESA/Hubble Observations of supermassive black…
