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 ..

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 ..
The Indian scientists at the Aryabhatta Research Institute of Observational Sciences (ARIES) have recently discovered 28 new variable stars in the Milky Way galaxy using 3.6 metre Devasthal Optical Telescope (DOT) established in 2016 near Nainital. The ARIES team of researchers was led by Dr. Sneh Lata and Dr. A K Pandey. It is for ..
The researchers at NASA space agency has found evidence for a unique mixture of methanol, water ice, and organic molecules on the surface of Ultima Thule, which is located in the Kuiper Belt – beyond the orbit of Neptune. The mixture is very different from most icy objects explored previously by spacecraft. Ultima Thule (also ..
NASA’s Cassini spacecraft has made an incredible observation about the extraordinary deep lakes filled with methane in the Saturn’s moon, Titan. Titan, Saturn’s largest moon has methane rain that can fill lakes as much as 330 feet deep. Titan has become only planetary body known to have stable liquid on its surface, apart from Earth.
By using data obtained by NASA’s Cassini spacecraft, the researchers discovered deep lakes (more than 300 feet, or 100 meters) filled with methane on Saturn’s moon Titan. The team also found “phantom lakes” that fill and empty periodically. It must be noted that Titan is the only known body in our solar system other than ..
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 ..
An international team of astronomers has discovered the most-distant object ever spotted in our solar system. It’s provisional designation is ‘2018 VG18’ & nicknamed as “Farout” for its extremely distant location. The pinkish dwarf planet is more than 100 times farther from the sun than Earth is — and almost four times more distant than ..
