STELLAR REMNANTS
NASA and AstroSat capture explosive eruptions from stellar remnants near massive black hole
An international team of astronomers, including experts from Pune¡¯s IUCAA, has made significant strides in understanding black hole-star dynamics. Observations of the star AT2019qiz revealed it collides with debris from a destroyed star every 48 hours, leading to bursts of X-rays. This research connects tidal disruption events and quasi-periodic eruptions, shedding light on their relationship and cosmic behavior.
Look up! A once-in-a-lifetime explosion is about to create a 'new' star in the sky
T CrB, a white dwarf in Corona Borealis, 3,000 light years away, will erupt soon with a magnitude 2.5 brightness due to a thermonuclear reaction. Drawing gas from a red giant, it formed an accretion disc and entered a high state in 2015. Both amateur and professional astronomers await this rare midnight sky event.
Step into Space with NASA's latest 3D video as it takes you through the cosmic 'Pillars of Creation'
NASA has unveiled a stunning 3D visualization of the 'Pillars of Creation' located in the Eagle Nebula, combining images from the Hubble and James Webb Space Telescopes. These cosmic structures, first captured by Hubble in the 1990s, have fascinated humanity for their towering columns of gas and dust where new stars are born. The new video allows viewers to explore these pillars in three dimensions, showcasing their intricate details and contrasting views from Hubble's visible-light images to Webb's infrared perspectives. This initiative aims to enhance public engagement and understanding of star formation processes, part of NASA's Universe of Learning initiative.

The global economy needs a new powerhouse. India is stepping up
Modi is closer than any predecessor to being able to claim that the nation ¡ª which may have just passed China as the world¡¯s most populous ¡ª is finally meeting its economic potential. To get there, he¡¯ll have to wrestle with the drawbacks of its exceptional scale: the remnants of the red tape and corruption that has slowed India¡¯s rise, and the stark inequality that defines the country.
Zombie worlds: Five spooky planets orbiting dead stars
Stars with more than about eight times the mass of the Sun will typically burn through their fuel in less than 100 million years. Once fusion ceases, the star collapses - generating a massive instantaneous final burst of nuclear fusion which causes the star to explode as a supernova.
