Hubble Telescope finds Water Vapour on Habitable-Zone Exoplanet

For the first time have Astronomers have discovered water vapour signatures in the atmosphere of a planet beyond our solar system that resides in the habitable zone (the region around a star which can support liquid water given sufficient atmospheric pressure). Discovery of Water Vapour in Habitable Zone The Astronomers from the Center for Space ..

Spektr-RG space telescope is a joint venture of Russia & Germany

The Spektr-RG space telescope is a joint venture of Russia & Germany that will map X-rays across the entire sky in unprecedented detail. It has been successfully launched into the space from the cosmodrome in Baikonur, Kazakhstan on 13th July 2019. The Spektr-RG is a space observatory intended to replace the Spektr-R (Known as the ..

L 98-59b, L 98-59c and L 98-59d

L 98-59b, L 98-59c and L 98-59d are new planets discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS). Features of the New Planets While L 98-59b is around 80% Earth’s size, L 98-59c and L 98-59d are around 1.4 and 1.6 times the Earth’s size respectively. L 98-59 is the host star of the three ..

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 ..

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 ..

AstroSat used by Indian astronomers to identify a new group of stars in globular cluster NGC 2808

By using Indian multi-wavelength space observatory AstroSat, the astronomers from Thiruvananthapuram and Mumbai have identified a new population of ultraviolet stars in the globular cluster NGC 2808. Globular clusters are collections of thousands to millions of stars, moving as one unit. These stars are tightly held together by gravity of the cluster itself, and are ..

NASA decides to launch SPHEREx Mission to investigate origins of our Universe

US space agency NASA has recently unveiled a new space telescope ‘SPHEREx’ that would begin a two-year mission in 2023 to map the entire sky in order to understand the origins of the universe. The acronym SPHEREx stands for ‘Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer’. The spacecraft’s objective ..

Star-Planet Activity Research CubeSat (SPARCS)

The spacecraft, known as the Star-Planet Activity Research CubeSat, or SPARCS, is a new NASA-funded space telescope and will be launched in 2021. It will monitor the flares and sunspots of small stars to assess how habitable the environment is for planets orbiting them. The heart of the SPARCS spacecraft will be a telescope with ..
