NASA’s new next-generation space telescope, currently under development, will see thousands of exploding stars called supernovae across vast periods and space.

Using these observations, astronomers aim to shine a light on several cosmic mysteries, providing a window onto the universe’s distant past and hazy present.

Supernovae, the dramatic deaths of stars, are most often associated with stellar explosions. Astronomers explored the firework-like debris from the birth of a group of huge stars and captured some spectacular photographs of the remnants of a 500-year-old eruption, showing that star forming can be a violent and explosive process as well.

Tracking a rare supernova explosion, Indian astronomers have traced it to one of the hottest kinds of stars, called Wolf-Rayet stars or WR stars.

The rare Wolf-Rayet stars are highly luminous objects a thousand times that of the Sun and have intrigued astronomers for long, the Union Ministry of Science and Technology said in a statement on Tuesday.

The uncertainty in Apophis' orbit has collapsed from hundreds of kilometres to just a handful of kilometres when projected to 2029. Pixabay

In a big relief, NASA has ruled out the possibility of asteroid Apophis impacting Earth in 2068, saying that our planet is safe from this notorious space rock for at least a century.

The results from a new radar observation campaign combined with precise orbit analysis have helped astronomers conclude that there is no risk of Apophis impacting our planet for the next 100 years at least, NASA said.

Polarisation allows astronomers to map the magnetic field lines present around the inner edge of the black hole. Pixabay

A new view of a supermassive black hole marks the first time astronomers have captured and mapped polarisation, a sign of magnetic fields, so close to the edge of a black hole.
Images released by the Event Horizon Telescope (EHT) collaboration revealed how the black hole, some 55 million light-years away at the center of galaxy M87 appears in polarised light.

The EHT collaboration involves more than 300 researchers from Africa, Asia, Europe, North and South America. Scientists still do not understand how magnetic fields — areas where magnetism affects how matter moves — influence black hole activity. Do they help direct matter into the hungry mouths of black holes? Can they explain the mysterious jets of energy that extend out of the galaxy’s core?
