TESS Mission of NASA discovers its first Earth-size planet – HD 21749c

The Transiting Exoplanet Survey Satellite (TESS) Mission of NASA has discovered its first Earth-size planet – HD 21749c. The newly-discovered planet is about 89% Earth’s diameter. The planet is likely very hot, with surface temperatures perhaps as high as 800 degrees F (427 degrees C). It orbits HD 21749, a K-type dwarf star located 53 ..

Astronomers capture first ever image of Black Hole

Astronomers have captured the first-ever image of a black hole, which is located in a distant galaxy known as ‘Messier 87’ (M87), through a network of 8 linked radio telescopes known as the Event Horizon Telescope (EHT) Collaboration. The black hole in the centre of M87 has a mass of more than six billion solar ..

MIT student creates an Algorithm that made first Black hole image

Computer scientist Katie Bouman, who is still a graduate student at MIT has developed the algorithm to create the first image ever of a black hole. Katie has named the algorithm ‘CHIRP’ (Continuous High-resolution Image Reconstruction using Patch priors) which was needed to gather data from 8 radio telescopes across the world working under Event Horizon ..

Earth’s fate predicted: Newfound tiny planet gives a glimpse

The ground based telescope picked up signals confirming planet revolving sun like star. The star belongs to the Milky Way galaxy. The star was identified using spectroscopic methods. It is in its white dwarf state. Eventually our sun is also likely to reach this stage in 5 billion years. As the star is running out ..

Scientists discover new Saturn like planet 60 times bigger than Earth

Astronomers have discovered a new exoplanet using NASA’s exoplanet-hunting space telescope, TESS. The exoplanet is said to be 60 times bigger than our planet and is five-billion-year-old planet. The exoplanet is dubbed TOI-197.0 or “hot Saturn” because of its size and hot temperature. The researchers at Aarhus University, say that this is “one of the ..
