Astronomers Find Exoplanet HD 63433 D With Lava Hemisphere

Astronomers have found another planet, which they are calling HD 63433 D. The planet is tidally locked, meaning there is a dayside which always faces its star and a side in constant darkness.This exoplanet is outside our solar system, and orbits around the star called HD 63433 (TOI 1726) in the HD 63433 system. Astronomers believe the exoplanet is younger than 500 million years old, which makes it the closets discovered earth-sized planet this young.The Astronomers analyzed this system using data from NASA's TESS Satellite, which spots planets when they cross in front of the star they orbit. The planet very close to the size of the Earth, with a diameter of 1.1 times the size of us. It's also orbiting a star that's similar to the size of our Sun. HD 63433 D orbits it's star much ...

Scientists Find a White Dwarf Star Turning Into a Diamond

Scientists have made an intriguing discovery in the realm of stars. They have identified a white dwarf star that is currently undergoing a fascinating transformation into a celestial diamond.This white dwarf star is essentially the remnants of a sun-like star that has depleted most of its fuel and collapsed. When the core of a star predominantly consists of metallic oxygen and carbon, the subsequent cooling process after it becomes a white dwarf can lead to the formation of an enormous diamond. However, this transformation occurs at an exceptionally sluggish pace, estimated to take one quadrillion years. Given that the universe is a mere 13.6 billion years old, it is unlikely that any star has completed this dazzling metamorphosis. (Just to clarify, a quadrillion equals one thousand t...

Astronomers Have Found 4 New Mini-Neptune Planets

Astronomers have made an exciting discovery by spotting four new "mini-Neptune" planets around a distant star. These exoplanets are categorized as mini-Neptunes, a class of planets smaller and located farther from their stars compared to hot Jupiters.The newly found planets revolve around different stars and have a size similar to that of Neptune or slightly smaller, ranging from two to five times the size of Earth. Two of these exoplanets orbit the same orange dwarf star called HD 15906, situated approximately 149 light-years away from our solar system.A team led by researchers from the University of Bern and the University of Geneva in Switzerland identified the mini-Neptune using the Characterising Exoplanet Satellite (CHEOPS), the European Space Agency's spacecraft dedicated t...

Astronomers Find Another Planet In The BEBOP-1 System

A team of astronomers from the University of Birmingham has made an exciting discovery in the BEBOP-1 or TOI-1338 system—a rare multiplanetary circumbinary system. Using the Doppler method, they have found a second planet, which they have named BEBOP-1c. This finding provides valuable insights into the formation of planets around binary star systems.(adsbygoogle = window.adsbygoogle || []).push({});Circumbinary systems are unique because planets orbit around two stars at their center, unlike our Solar System where planets orbit around a single star. The researchers' findings have been published in the latest issue of the journal Nature Astronomy.The newly discovered planet, BEBOP-1c, is named after the project that collected the data—Binaries Escorted By Orbiting Plane...

Astronomers Found New Earth Sized Planet Called LP 791-18 D

Another earth-sized exoplanet has been found beyond our solar system, and astronomers are calling in LP 791-18 D.The planet is most likely covered with volcanoes, but also has the possibility to support life. What a strange combination. It also seems to be a bit like Jupiter's Moon IO - it could have volcanic outbursts just like it.The planet was found with ground-based observations made by the Center for Astrophysics at Harvard & Smithsonian. They used a combination of space and ground-based observations, and used data from NASA's Transiting Exoplanet Survey Satellite, as well as the Spitzer pace Telescope. To find the mass of the planet, the team measured tiny differences in the time it takes the planet to orbit it's host star from one orbit to the next one.LP 791-18 D...
