Two (potentially) exciting new exoplanet discoveries
Scientists just announced 2 new exciting updates about exoplanets. One is a potentially habitable world similar in size and temperature to Earth. The other is a possible new planet – possibly with rings – orbiting the closest star to our sun, Proxima Centauri.

Ten-Minute Coronavirus Test For $1 Could Be Game Changer
An anonymous reader quotes a report from Bloomberg: Already exhausted from testing for monkeypox and Lassa fever, Nigerian molecular bio-engineer Nnaemeka Ndodo had to work well past midnight earlier this month to find out if six Chinese construction workers were infected with the coronavirus. Ndodo had to collect samples from a hospital an hour away in Nigeria’s capital, Abuja, then wait…
Discovery points to origin of mysterious ultraviolet radiation
Billions of lightyears away, gigantic clouds of hydrogen gas produce a special kind of radiation, a type of ultraviolet light known as Lyman-alpha emissions. The enormous clouds emitting the light are Lyman-alpha blobs (LABs). LABs are several times larger than our Milky Way galaxy, yet were only discovered 20 years ago. An extremely powerful energy source is necessary to produce this…
