    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...

  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...

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...

    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...

Vice President Kamala Harris and French President Emmanuel Macron previewed a new image of a pair of galaxies from the Webb telescope’s MIRI and NIRCam cameras. A merging galaxy pair cavort in this image captured by the James Webb Space Telescope, an international mission led by NASA with its...

  2022 WJ1 was a tiny asteroid on a collision course with Earth. But astronomers saw it coming, and NASA’s Scout impact hazard assessment system calculated where it would hit. In the early hours of Saturday, Nov. 19, the skies over southern Ontario, Canada, lit up as a tiny asteroid harmlessly...

An asteroid the size of a delivery truck will pass Earth in one of the closest such encounters ever recorded – coming within a tenth of the distance of most communication satellites’ orbit. NASA said the newly discovered asteroid would pass 2,200 miles (3,600km) above the southern tip of South...

  A case study involving Europe’s largest coal-fired power plant shows space-based observations can be used to track carbon dioxide emissions – and reductions – at the source. A duo of Earth-observing missions has enabled researchers to detect and track carbon dioxide (CO2) emission changes...
