The UR Rao Satellite Centre has announced a brand new discovery by the XSPECT device aboard India's XPoSat satellite.
On march 19, 2025, XSPECT detected a rare thermonuclear "burst"
followed quickly by way of a far longer and extra effective occasion known as a "superburst" from a neutron megastar device named 4U 160852, located approximately 4,000 light-years from Earth.
Neutron stars are surprisingly dense remnants of huge stars that exploded as supernovae.
They may be only approximately 10 to 20 kilometers extensive but weigh more than our solar system. In some instances, those neutron stars exist in binary systems, where they pull gas from a nearby companion superstar.

This gas builds up at the neutron celebrity's surface and heats up to tens of millions of degrees, emitting X-rays.
Now and again, the fuel layer ignites abruptly in a thermonuclear explosion, inflicting a quick X-ray burst lasting seconds to minutes.
This is what XSPECT discovered first—a short burst peaking in only some seconds and fading over approximately 20 seconds. Then, enormously, about 16 minutes later, the celebrity brightened again; however, this time the burst lasted for approximately 3 hours.
This longer occasion is called a superburst and is resulting from the explosive burning of carbon deep underneath the floor. Superbursts are very rare as compared to normal bursts.
XSPECT's detailed observations confirmed the neutron superstar's surface temperature throughout the bursts reached around 20 million Kelvin, with a radius near 9.3 kilometers.
The statistics additionally recommend unique processes like Compton scattering, which is probably involved in the superburst's high brightness and sluggish fade.
India's XSPECT tool aboard the XPoSat detected a rare thermonuclear burst.
This discovery is vital because it allows scientists understand the intense physics of neutron stars and the behaviour of remember under intense gravity and warmth.
The superburst became additionally visible by using another space tool, MAXI, confirming the event.
XSPECT's potential to study X-rays without saturation and over lengthy periods makes it uniquely suited to capture such uncommon activities.
The group plans to continue analyzing these bursts to learn more about the acute environments around neutron stars and the approaches powering those cosmic explosions.
