The Hubble Space Telescope Spots Farthest Star Ever Seen
NASA announced a new record today. The light that began its journey from a star 12.9 billion years ago has reached the Hubble Space Telescope, making it the furthest star humans have ever seen. That means this particular star existed within the first billion years of the universe's existence. The star has been dubbed Earendel, which is an Old English word for morning star. Earendel is (or was 12 billion years ago) more than 50 times as big as our sun, and millions of times brighter. Since it is so distant and so old, it may be made up of different material than more familiar stars. The previous record for the most distant star ever seen was a four-billion-year-old star detected in 2018. The new star Earendel is ripe for study, as NASA’s James Webb Space Telescope will be focusing on it for more information. Read more about the discovery of Earendel and what it tells us about the early universe at NASA. -via reddit#star #Hubble #NASA #Earendel
December Stargazing: Meteors and Comets and Planets, Oh My!
This month will be a full one for people who want to see things up in the night sky. On December third, the planet Venus will shine its brightest of the year, but will be visible for a few weeks afterward as well. We have two, count 'em, two meteor showers you'll want to see. And there's a chance we'll be able to spy Comet C/2021 A1, affectionally known as "Leonard," on December 9th. There's a solar eclipse, too, but you'd have to be in Antarctica to see its totality. Besides that, there's the winter solstice and the Christmas star (Sirius) and a few other heavenly events you'll want to mark on your calendar. Dig out the binoculars (or a telescope if you have one), and make plans to get away from city lights. Get a full list with links and instructions for viewing these December celestial events at Lifehacker.#meteorshower #star #comet #stargazing
When Stars Die, Collapse, and Become Frozen
Stars can last for billions of years, but like anything that's burning, they will all eventually run out of fuel. A fuel-depleted star will collapse and become a white dwarf star, but that's not its ultimate fate. SciShow explains what is happening inside when a star burns out and eventually collapses.
STARFORGE: A Simulation of How Stars Form
How do stars form? This video clip from STARFORGE (Star Formation in Gaseous Environments), you can see the simulation of a gas cloud 20,000 times the mass of the Sun. Within 2 million years, the gas cloud condenses under its own gravity to form the first stars. Newly formed massive stars started to expel stellar jets.#star #StarFormation #starforge #spaceVideo credit: Michael Y. Grudic (Northwestern U.) et al., STARFORGE Collaboration
