Stellar Evolution In 5 Minutes

Stars are born from cold clouds of dust and gas that collapse under the force of gravity. How a star goes through life depends on its initial mass. Mass is how much matter a star has which is often related to its size. Hydrogen, the simplest of the elements, is the fuel stars “burn” to…

Newfound Planet Only 11 Light Years Away Could Support Life

Planets, planets everywhere and here and there an Earth. Astronomers announced the discovery this week of a new, temperate Earth-sized planet only 11 light years away orbiting the star Ross 128 in the constellation Virgo. After Proxima b, the planet circling Proxima Centauri in the Alpha Centauri triple star system, it’s the closest, potentially life-friendly…

What’s The Smallest Star? EBLM J0555-57Ab Of Course!

Just slightly larger than Saturn, EBLM J0555-57Ab is the smallest star ever found. We’re talking a living star that fuses hydrogen into helium to make energy, not a white dwarf or neutron star, which long ago exhausted its fuel. While these unusual stars can be as small as a large city, they don’t qualify because they no longer…

Alien Solar System Amazes With Seven Earth-Sized Planets

It took decades to find the first Earth-sized planet. Now, astronomers have found seven of them in one fell swoop! They orbit the cool (literally cool) red dwarf star, TRAPPIST-1, 40 light years away in the constellation Aquarius. Using ground and space telescopes, the planets were all detected as they passed in front of their parent star, causing its…

Earth-Like Planet Discovered In Habitable Zone Of Nearest Star

Amazing news! Today, a team of European astronomers announced the discovery of a potentially habitable planet around Proxima Centauri, the nearest star beyond the sun. That planet, called Proxima b, is at least 1.3 times the mass of Earth and squarely located within the star’s habitable zone, where temperatures are clement enough for liquid water…
