Since the late 1800s, observers have searched the polar skies for elusive, high-flying clouds that shine in the darkness. These polar mesospheric clouds, or PMCs,…
One of the first things people want to know before taking a trip is what the weather will be like wherever they are headed. For…
Using information from ESA’s Swarm satellite constellation, scientists have made a discovery about how energy generated by electrically-charged particles in the solar wind flows into…
Robust stellar flares might not prevent life on exoplanets, could facilitate its detection. Although violent and unpredictable, stellar flares emitted by a planet’s host star…
Proxima Centauri is the closest star to the Sun, and its planet, Proxima Cen b (“Proxima b”), lies in its habitable zone (the distance range…
Stellar Flares With a Chance of Radio Bursts: The Weather From Proxima Centauri A discovery that links stellar flares with radio-burst signatures will make it…
Planetary habitability, defined by a planet’s ability to sustain liquid water on its surface, is one of the most important concepts in exoplanet science. Exoplanets…
The Sun has entered its 25th solar cycle and is about to wake up. For the last few years our star has been pretty sleepy,…
Solar Cycle 25 has begun. During a media event on Tuesday, experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) discussed their analysis…
National Science Foundation awards proposal for space weather modeling. On a moonless night on August 28, 1859, the sky began to bleed. The phenomenon behind…
200 years of sunspot observations used by University of Warwick researchers to create ‘sun clock’ Sun clock pinpoints times of sharp switch on and off…
Nearly a millennium and a half ago, red light streaked the night sky over Japan. Witnesses compared it to the tail of a pheasant —…
In October 2018, we’re launching the Ionospheric Connection Explorer, or ICON, to study Earth’s dynamic interface to space. Its combination of remote and in situ measurements will…
Living near a star is risky business, and positioning a spacecraft near the Sun is a very good way to observe rapidly changing solar activity…
NASA’s Solar Dynamics Observatory captured an image of a mid-level solar flare emitted from the sun on September 4th. The sun emitted a mid-level solar…
Astronomers may now be able to explain why the Sun’s magnetic field reverses every eleven years. New research explains how the duration of the magnetic…
Scientists review the fundamental physical process behind space weather events that are linked to human activity and discusses the observations of their impacts. Our Cold…
A newly published study details the anthropogenic effects on the space environment, which started in the late 19th century and reached their peak in the…
