Gaia Mission

Gaia is a space observatory of the European Space Agency (ESA) which was launched in 2013.

Gaia mission has found parts of the Milky Way galaxy are much older than expected.

According to the data received from Gaia, the Milky Way is 2 billion years earlier than expected

and just 0.8 billion years from Big Bang!

Odd Radio Circles Could Come From Giant Black Holes?

According to new study, Odd Radio Circles (ORCs) are rings of faint radio signals which are surrounded to a galaxy with a giant blackhole with very strong gravity at its center.

This new study says ORCs comes from giant black holes in space.

Jupiter's Moon Europa could be feeding life below the ice

An artist's interpretation of frozen water on Europa's surface credit : NASA As we know life needs three main components liquid water, appropriate chemical composition, and a source of energy. Astrobiologists - sc ientists who study the origin, evolution, and future of life in the universe - believe that Europa has water and the right chemical compositions but it's difficult to confirm the energy source on Europa. On Earth we found life near subterranean volcanoes, deep sea vents, and in other extreme environments. We say them 'Extremophiles'. These life forms give scientists clue about how life can be possible beneath the ice shell of Jupiter's Moon Europa. A research shows Europa is pulling down the oxygen below the icy shell, where it could be feeding the life (the simple life). Hypothetical ocean crybot of the Jupiter's moon Europa, credit: NASA The frozen moon have oxygen at its surface, another hint of life. This oxygen is generated when the sunlight...

"Meteor like object" streaking across Gujrat night sky

Meteor like object in the sky of Gujrat In Vadodara/ Surat / Rajkot on Saturday night, a humongous Meteor like object lightened the sky. While in some parts of Gujrat, people reported an unidentified object 'coming down from the sky'. They said the object was like a ball of fire that distressed into two parts in the sky. Scientists said object can only be labelled after the study of the debris. "It can be a meteor or can be space debris", Astrophysicist and cosmologist Dr. Pankaj Joshi said. "When any objects fall down from space towards earth it experiences atmospheric friction, which causes the debris burn. And that debris attains a very high through the gravitational force of Earth and emits a much light in the sky. Small debris only left for some of the seconds. But the big debris can be harmful to us as it lasts for much of the time and don't burn by the atmospheric friction." Another theory is saying, it can be a unidentified space object. Most of...
