The cost of encryption technologies has been a barrier. Many of the products now available to make satellite communications encrypted are expensive and out of reach for many commercial space firms. The post Space sectors...

MOUNTAIN VIEW, California - Investors are backing space companies with defense-related business lines. In many cases, growing Department of Defense interest in commercial space technologies is benefiting the most well-fu...

A tiny dim satellite galaxy of the Milky Way doesn't have enough stars to hold itself together. Its properties suggest that its dark matter halo is holding it together, but new research counters that. Researchers say...

Japan declared its Akatsuki spacecraft dead on Tuesday (Oct. 28), more than a year after the Venus climate probe failed to respond to calls from mission control.

Saudi telecoms giant stc Group has signed a 10-year agreement that includes a $175 million prepayment commitment to use AST SpaceMobiles planned space-based cellular broadband network, the Texas-based venture announced O...

Researchers claim flashes of light seen in sky surveys could have been UFOs drawn to Earth by nuclear tests, but more mundane explanations should be explored first.

The Milky Way is a rich and complex environment. We see it as a luminous line stretching across the night sky, composed of innumerable stars.

Using the James Webb Space Telescope, scientists mapped the ultra-hot Jupiter WASP-18b in three dimensions, uncovering a blistering hotspot where water molecules are torn apart.

The Habitable Worlds Observatory (HWO) is slated to be the next Great Observatory for the world. Its main focus has been searching for biosignatures in the atmospheres of at least 25 Earth-like exoplanets. However, to do...
