The Hubble Space Telescope recently captured the appearance of several asymmetrical ‘spokes’ rising above the rings of Saturn, marking a coming change in season for the ringed gas giant. The spokes are made of charged ice particles bulging up and away from the rest of the rings. Researchers aren’t sure exactly what causes the spokes, …

Even on a sunny day, human eyes can’t see all the light our nearest star gives off. A new image displays some of this hidden light, including the high-energy X-rays emitted by the hottest material in the Sun’s atmosphere, as observed by NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR). While the observatory typically studies objects outside …

Using the AstroSat satellite, astronomers from the University of Calgary, Canada, have identified 20 supernova remnants (SNRs) in the Andromeda Galaxy, which exhibit diffuse ultraviolet emission. The finding, presented in a research paper published January 25 on the arXiv preprint server, could help us better understand the origin and properties of ultraviolet emission …

On 27 January 2023, the Angolan president, João Lourenço, inaugurated the nation’s first satellite Mission Control Center (MCC) in Funda, Luanda. The MCC is an essential infrastructure capable of operating three satellites simultaneously and would be used to monitor the activity of the ANGOSAT 2, launched on 12 October 2022. The launch ceremony was …

Astronomers are finding new exoplanets almost every day, but due to the incredible distances between star systems, space exploration has been limited to our solar system. For example, it is estimated that the Voyager 1 spacecraft, presently traveling away from the sun at 10.7 miles per second (17.3 kilometers per second), would take over 73,000 …

In its violent early years, Earth was a molten hellscape that ejected the moon after a fiery collision with another protoplanet, scientists now suspect. Later, it morphed from a watery expanse to a giant snowball that nearly snuffed out all existing life. Then hyper-hurricanes with waves as high as 300 feet pummeled the …
