Does our Oort Cloud overlap with Alpha Centauri’s?
About 2,000 to 5,000 astronomical units (AU; where 1 AU is the average distance between Earth and the Sun) from the Sun lies the beginning of the Oort Cloud. For context, the Voyager spacecrafts —...![Astronomers in India discover a new ghost galaxy](https://greenarea.com.lb/wp-content/uploads/2022/04/Screenshot-2022-04-05-205409-1080x521.png)
Astronomers in India discover a new ghost galaxy
India’s astronomers have discovered a galaxy that lies in front of a larger, brighter galaxy that had previously been undiscovered. 136 million light-years from us, the galaxy has a ghostly...![Astronomers launch new asteroid-classification system based on animal sizes](https://greenarea.com.lb/wp-content/uploads/2022/04/iStock-1316779160-lores-635x357.jpg)
Astronomers launch new asteroid-classification system based on animal sizes
A new system for classifying the sizes of small planetary objects using animals has been launched by the European Space Agency (ESA) in a bid to clear up misconceptions introduced after an asteroid...![FLOOFY OBJECTS AND OTHER TALES OF ASTRONOMICAL IMPOSSIBILITY](https://greenarea.com.lb/wp-content/uploads/2022/04/Taurine-HLTau-502x600.jpg)
FLOOFY OBJECTS AND OTHER TALES OF ASTRONOMICAL IMPOSSIBILITY
Astronomers aren’t holding back this year, with brand-new submissions to this year’s highly prestigious (and fictitious) Acta Prima Aprilia. The skills astronomers learn in critical thinking,...![Hubble spots the farthest star ever seen](https://greenarea.com.lb/wp-content/uploads/2022/03/Earendelfartheststar.jpg)
Hubble spots the farthest star ever seen
At the risk of sounding like a broken record, NASA’s Hubble Space Telescope has broken another record. The Hubble Space Telescope has imaged the most distant star ever seen, according to a study...![Astronomy & Astrophysics 101: Gravitational Waves](https://greenarea.com.lb/wp-content/uploads/2022/03/Gravity-Waves-Black-Hole-Merger-777x437.jpg)
Astronomy & Astrophysics 101: Gravitational Waves
Gravitational waves are not simple conceptually, as they require one to think of the fabric of the Universe in terms of spacetime. Spacetime is a four-dimensional quantity, described by Einstein’s...![Astronomers spot a vast, mysterious circle in space](https://greenarea.com.lb/wp-content/uploads/2022/03/d41586-022-00861-6_202459441-720x720.jpg)
Astronomers spot a vast, mysterious circle in space
Astronomers have spotted an enormous and mysterious object more than a million light-years across, called an odd radio circle (ORC). ORCs were first identified in 2019, and now researchers have...![Starlink satellite streaks: How big of a problem are they?](https://greenarea.com.lb/wp-content/uploads/2022/03/Picture1.jpg)
