The satellites in Amazon's new internet-beaming megaconstellation in low Earth orbit are bright enough to disrupt ...

A Simon Fraser University cosmologist believes his team's new research may bring them a step closer to cracking one of science's biggest questions—the Hubble tension.

Launched between 1971 and 1987 primarily to collect intelligence data on foreign weapon testing, the last satellites in the JUMPSEAT family were withdrawn from service in 2006. A memorandum dated Dec.

The idea sounds simple enough when reduced to its basics. Put reflective surfaces in orbit and redirect sunlight back to Earth after sunset. A Califor.

NASA's Perseverance rover discovered rocks on Mars, providing new evidence the red planet was once a wet, habitable world that could support life.

Light is the fastest phenomenon in the universe, clocking in at just under 300,000 kilometers per second. The telescopes that observe that light, from radio waves to gamma rays, are built at rather ...

Research finds Amazon’s LEO internet satellites can disrupt ground- and space-based astronomical observations due to brightness levels exceeding IAU recommendations.

The study analyzed 1,938 observations of Leo satellites orbiting at 630 km, and found that they have an average magnitude of ...

A recent ArXiv-published study has found that Amazon’s new internet-beaming satellites may pose a risk to astronomical ...
