Life on Mars? Bacteria may have survived under its surface for 280 million years

Is there life on Mars? This question has been bugging scientists and commoners alike for ages. Well, there just might be, because a new study says microorganisms may be able to survive just beneath the Martian surface, shielded from the harsh radiation of space, much longer than previously thought. The journal Astrobiology on Tuesday published t...

Researchers study microbial interactions in International Space Station

Along with opening the doors of space travel to the common people, researchers are also continuing with their efforts to ensure safe travel into space. Researchers at the Indian Institute of Technology Madras (IIT Madras) and NASA Jet Propulsion Laboratory (JPL) have studied the interactions between microbes in the International Space Station (I...

Early warning system to alert when a star dies in a supernova explosion

Scientists have now found a way to watch the explosive death of a star, known as a supernova explosion, in real time. Astronomers from the Liverpool John Moores University (LJMU) and the University of Montpellier have developed an “early warning” system, which can alert when a massive star is on the verge of dying in a supernova explosion. This ...

Alien spotting enabled using earth’s varying oxygen levels data

Are we alone in the universe? This is a question that has intrigued humans for centuries and inspired countless studies and works of fiction. But are we getting closer to finding this out? Now that the James Webb Space Telescope (JWST) is in operation, we might have taken one giant leap in being able to answer this one day. One of the four main ...
