Discoveries made from outside our planet, however, are even harder, especially when these discoveries that are several thousand light years away. With the advancement in technology and interest in the field, black holes are becoming more and more popular in the scientific community.

Newfound black hole may be the closest to Earth

Newfound black hole may be the closest to Earth Dan Falk © Illustration by Lauren Fanfer and Ohio State University. TK How small can a black hole be? For several decades, astronomers have worked to answer this question by tallying the black holes in our corner of the universe. They’ve found plenty of big and medium-size ones over the years including a supermassive monster at the heart of our galaxy. But until recently, they’ve seen no signs of small ones, and that’s presented a long-standing mystery in astrophysics. The discovery “implies that there are many more [small black holes] that we might find if we increased the volume of space that we searched,” says Tharindu Jayasinghe, an astronomer at Ohio State University and lead author of a new paper detailing the discovery in the

Study by Indian Astronomers provides clues to explosion mechanism of supernovae that are key measure of cosmological distances

Share New Delhi: In 2011, the Nobel Prize was awarded to three scientists for discovering that the Universe is expanding at an ever-accelerating rate through observations of distant supernovae. Now a team of Indian astronomers observing such distant supernovae have narrowed down the possible mechanisms of explosion of such supernovae which provide key measures of cosmological distances. Their detailed study of a supernova called SN 2017hpa, a particular type of supernovae called I a supernova, which exploded in 2017 helped narrow down the explosion mechanism of the supernovae by observations of unburned carbon in the early phase spectra. The explosive death of a star as a supernova is one of the most spectacular and catastrophic events in the Universe. Type Ia supernovae are the result of explosions of white dwarfs that exceed their mass beyond the Chandrasekhar limit through accretion of matter. Their homogeneous nature makes them extremely good standardizable candles to mea
