New research from the University of Toronto shows that from approximately 2 billion until 600 million years ago, an atmospheric tide driven by the Sun...
Coronal rain is the most dramatic display of cooling in the Sun’s corona. It corresponds to cool and dense clumps of plasma appearing over a timescale...
NASA’s Parker Solar Probe has flown close enough to the Sun to detect the fine structure of the solar wind close to where it is generated at the solar...
New images from the Visible-Broadband Imager (VBI) on NSF’s 4-m Inouye Solar Telescope show a variety of sunspots and quiet regions of the Sun.

Glacial cycles during the Early Pleistocene epoch are characterized by a dominant 41,000-year periodicity and amplitudes smaller than those of glacial...
Life most likely started during the Hadean Eon (4.5 to 4 billion years ago). However, the environmental conditions which contributed to the complexity...
New research shows that Phaethon’s comet-like activity cannot be explained by any kind of dust.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected gaseous water in the planet-forming disk around V883 Orionis, a...
‘Sun rays’ are also known as crepuscular rays, from the Latin word for twilight. It was the first time sun rays have been so clearly viewed on Mars.

In new research, paleontologists analyzed abundances of sunscreen-like chemicals in 800 fossil pollen grains from 250-million-year-old rocks in Tibet.
The...
The accurate agricultural calendar allowed the ancient inhabitants of the Basin of Mexico to plan their agricultural cycle to feed one of the largest population...
Astronomers using the Dark Energy Camera (DECam) on the Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory have discovered two...
A light pillar is an optical phenomenon where a column of light can be seen emanating from a light source. If the light comes from the Sun, the phenomenon...
Solar switchbacks are sudden, large radial deflections of the solar wind magnetic field, previously revealed in interplanetary space by NASA spacecraft.
This...
With an age of 4.57 billion years, the Sun is currently in its comfortable middle age, fusing hydrogen into helium and generally being rather stable; staid...
WISE 1810055-1010023 (WISE 1810 for short), a metal-poor brown dwarf located 8.9 parsecs (29 light-years) away, is nearly 10 billion years old.
