Highlights RSS
Selections from 2023: A Dusty, Elongated Gas Cloud in the Galactic Center
A gas cloud near the galactic center, headed for destruction in 2036, may have been ejected during a recent stellar merger.
Selections from 2023: Do Waves or Nanoflares Heat the Solar Corona?
A massive study of solar flares allowed researchers to assess whether nanoflares are solely responsible for heating the solar corona.
Selections from 2023: The Coolest Sub-stellar Source of Radio Waves
Researchers have discovered and characterized the smallest and coolest radio-emitting sub-stellar object — a brown dwarf with spectral type T8.
Selections from 2023: Living on the Edge of Night and Day
On some exoplanets, a narrow region where it’s permanently dawn or dusk may be the only place that’s habitable. The amount of water on these planets plays a surprising role in whether it stays that way.
Selections from 2023: Surveying the Galactic Plane
More than 3 billion objects have been catalogued in the Dark Energy Camera Plane Survey, which this year released its second batch of data.
Selections from 2023: A Mysterious Nebula Near Andromeda
Though the Andromeda Galaxy has been photographed countless times, a team of amateur astronomers has found that it still holds some mysteries.
Selections from 2023: Sharpening Our Images of a Supermassive Black Hole
In April 2019, the Event Horizon Telescope collaboration released the first image of a supermassive black hole. This image was far from the last, and new algorithms have brought the data into sharper focus.
JWST: The World’s Most Sophisticated Carbon Monoxide Detector
Astronomers were pretty sure that WASP-39 b’s atmosphere was filled with carbon monoxide. Now, thanks to innovative use of a technique that hadn’t previously been used on JWST data, they’ve found it.
Monthly Roundup: The Sun, Space Weather, and Solar Flares
Four research articles take on small-scale phenomena in coronal plumes, the question of magnetic reconnection, red-winged flares, and solar wind forecasts.
Siblings or Only Children: M-dwarf Planets
Astrobites reports on the differences between planets orbiting M dwarfs in single-planet and multi-planet systems.
Featured Image: Surveying the Milky Way’s Faint X-ray Sources
The first phase of a survey designed to discover faint X-ray sources in our galaxy is complete, resulting in the discovery of hundreds of new sources.
