The hot-Jupiter exoplanet HIP 67522b orbits its parent star, HIP 67522, so tightly that it appears to cause frequent flares from the star’s surface,...
Since the Big Bang, the early Universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in...
Proxima Centauri’s flaring activity has been well known to astronomers using visible wavelengths, but new observations with the Atacama Large Millimeter/submillimeter...
Using sensitive instruments onboard ESA’s International Gamma-Ray Astrophysics Laboratory (Integral) mission, astronomers have detected a gamma-ray burst...
Fast radio bursts are extragalactic transient phenomena that shine in radio wavelengths for short durations lasting only 1-10 milliseconds. Some sources...
Extreme ultraviolet images of the Sun obtained by the Extreme Ultraviolet Imager (EUI) instrument onboard the ESA/NASA Solar Orbiter spacecraft have revealed...
Life most likely started during the Hadean Eon (4.5 to 4 billion years ago). However, the environmental conditions which contributed to the complexity...
The giant gamma-ray flare event, designated GRB 2001415, was emitted by a powerful magnetar in NGC 253, an active starburst galaxy approximately 11 million...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have studied large, long-duration flares in white light on red dwarfs, a class...
Using the Australian Square Kilometre Array Pathfinder (ASKAP), the Atacama Large Millimeter/submillimeter Array (ALMA), the NASA/ESA Hubble Space Telescope,...
Astronomers have detected a bright, long-duration optical flare accompanied by intense radio bursts from Proxima Centauri, the Sun’s nearest stellar...
In a new study published in the Astrophysical Journal Letters, astronomers investigated the effects the activity of the red dwarf star Proxima Centauri...
Barnard’s star, a 10-billion-year-old red dwarf just 6 light-years from Earth, is still very active and potentially destructive for the atmospheres of...
A team of astronomers in Japan has detected 12 stellar flares, including a so-called superflare, on AD Leonis, an M-dwarf star located just 16 light-years...
Using data from the European Photon Imaging Camera (EPIC) onboard ESA’s XMM-Newton X-ray observatory, astronomers have detected for the first time a...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have detected 1,216 superflare events on 400 solar-type stars. One of these stars,...
Coronal mass ejections (CMEs), often associated with solar flares, are the most powerful magnetic phenomena occurring on the Sun. Now, astronomers using...
A team of astronomers from the United Kingdom and Germany has spotted a superflare coming from an L-dwarf star approximately 250 light-years away that’s...
Stellar superflares from young red dwarfs may make conditions uninhabitable on fledgling planets, according to the new results of the Habitable Zones and...
