Massive Stars May Commit Grand Theft Planet

by Kimberly M. S. Cartier 23 September 202223 September 2022

New simulations show that planets around young, massive stars may have been captured or stolen rather than homegrown.

Shake, Rattle, and Probe

by Damond Benningfield 25 August 202217 January 2023

Helioseismology allows scientists to study the interior of the Sun, solve some basic physics mysteries, and forecast space weather.

In this digital illustration, three small rocky planets orbit a pulsar. One planet is large in the foreground and has a polar aurora and cratered surface. The other two are smaller in the background. A pulsar appears at top left in the image and is depicted as a bright white point source emitting white beams at 5 o’clock and 11 o’clock. Purple and green loops and swirls surround the point of light and represent the strong magnetic field of a pulsar.

Coronal Dimmings Shine Light on Stellar CMEs

by Jenessa Duncombe 6 June 202225 August 2022

Coronal mass ejections from stars have eluded easy observation, so scientists are looking at what’s left behind.

Exoplanets in the Shadows

by Damond Benningfield 26 July 202125 October 2021

The bright clutter of individual discoveries can overshadow some fascinating research, from necroplanetology to rogue planets to the intimacy of alphanumeric nomenclature.

Thousands of Stars View Earth as a Transiting Exoplanet

by Katherine Kornei 22 July 202110 January 2023

Researchers have identified more than 2,000 stars whose past, present, or future vantage points afford a view of Earth passing directly in front of the Sun, a geometry useful for pinpointing planets.

The supergiant Betelgeuse glows red and orange against a dark, starry background. The star’s surface is mottled and emits a faint reddish glow representing its stellar wind. A dark cloud of dust partially obscures the star’s lower left region.

When Betelgeuse Won’t Explode, You Need a Big Telescope to Prove It

by Kimberly M. S. Cartier 30 June 202126 January 2022

Thanks to last-minute telescope time, researchers pieced together the sequence of events that caused Betelgeuse’s Great Dimming last year.

Record-Setting Flare Spotted on the Nearest Star to the Sun

by Katherine Kornei 24 May 202128 April 2022

Proxima Centauri recently let loose a blast of radiation, and ground- and space-based telescopes detected the record-setting event at wavelengths ranging from radio to the ultraviolet.
