Study on Titan’s Energy Budget

A recent study published in the journal Geophysical Research Letters drew parallels between the energy budgets of Earth and the Saturnian moon Titan. Energy budget is the differences between the quantum of solar energy received and emitted by a planetary system or satellite system. Titan is the largest moon of Saturn. It is also the ..

NASA’s New Horizons mission gets a brand-new name “Arrokoth”

The International Astronomical Union and Minor Planets Center, the global body for naming Kuiper Belt objects, has finally given a name for the most distant world ever explored by a space mission. It is called Arrokoth. NASA launched the New Horizons mission in January 2006. After crossing by Pluto in 2015, in 2019 it flew by ..

Scientists discover water vapor in atmosphere of a super-Earth “K2-18b”

For the first time, the astronomers at the University College London have discovered water vapour in the atmosphere of an Earth-size planet called K2-18b. They used data from NASA’s Hubble Space Telescope. The exoplanet “K2-18b” is 8-times the mass of Earth and known as a super-Earth. It orbits a red dwarf star 110 light-years away ..

NASA discovers first nearby super-earth planet GJ357d

The NASA scientists have characterized the first potentially habitable world outside our own solar system that may be suitable for life. The super-earth planet — named GJ 357 d — was spotted by NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. It is estimated that planet is about six times the size of our planet and ..

NASA announces its New Frontiers program

NASA has recently announced its New Frontiers program, called Dragonfly mission, to explore Saturn’s largest moon – Titan. It’s the only moon in our solar system that has an atmosphere.The rotorcraft will fly to dozens of promising locations on Titan looking for pre-biotic chemical processes common on both Titan and Earth. The mission will launch ..

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 ..

The researchers at University of Warwick in UK discover a rogue exoplanet

The researchers at the University of Warwick in the UK have discovered a rogue exoplanet – NGTS-4b – with its own atmosphere in the Neptunian Desert. The Neptunian Desert is the region close to stars where no Neptune-sized planets are found. This area receives strong irradiation from the star, meaning the planets do not retain ..

NASA reveales that giant asteroid 99942 Apophis is expected to fly close to Earth in a decade

According to the latest data from US space agency NASA, the giant asteroid named 99942 Apophis is expected to approach dangerously close to the Earth on April 13, 2029. However, there is no need to worry as it will be about 31,000km away from the surface of the Earth. This is going to be a ..
