A star dies when it exhausts its nuclear fuel, causing it to either quietly cool into a dense remnant or collapse under its own gravity and explode into a brilliant #Supernova.

#KnowledgeByte: A #Supernova is the explosion of a star. It is the largest explosion that takes place in space.
A supernova occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion.

A cosmic first: separated sibling stars reunited by supernovae
We've never witnessed a pair of massive, binary stars both go supernova before.
Opposite the galactic center, we just might have spotted the ultimate family reunion: in death.

99% of a core-collapse supernova’s energy is invisible
Despite how luminous core-collapse supernovae are, 99% of the energy they carry away is invisible: in the form of neutrinos.
Here's why that must be the case.

“… Roman is set to launch on August 30, 2026, and will help us gain a wider view of the universe and collect data faster than its predecessors, such as the Hubble Space Telescope. The telescope will do so thanks to the incredible equipment and instruments built into it.
These instruments include the primary mirror, which was gifted to NASA by a U.S. intelligence agency, the Wide Field Instrument, and an advanced coronograph. Altogether, these instruments could help us map out more of the universe than we ever imagined.
“It is an incredible feat of precision engineering. It's quite possibly the most complex scientific instrument that NASA has ever built,” Dominic Benford, …program scientist for the Nancy Grace Roman Space Telescope…”

“Named after NASA’s first chief astronomer, the ‘mother of the Hubble Space Telescope,’ the Nancy Grace Roman Space Telescope will have a field of view at least 100 times larger than Hubble's, potentially measuring light from a billion galaxies in its lifetime. This observatory will also be able to block starlight to directly see exoplanets and planet-forming disks, complete a statistical census of planetary systems in our galaxy, and settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics…”
--
The Roman Space Telescope is engineered to investigate the biggest mysteries in astrophysics:
• Dark Energy & Dark Matter: By surveying billions of galaxies and mapping their distribution, Roman will explore why the universe's expansion is accelerating and trace cosmic history.
• Exoplanets: It will utilize gravitational microlensing to complete a statistical census of planetary systems in our galaxy, aiming to find thousands of exoplanets, including elusive rogue planets.
• Infrared Astrophysics: The telescope's deep, crisp infrared vision will help astronomers measure light from up to a billion galaxies over its lifetime.

#PhotoOfTheDay: NASA’s IXPE Gets Fresh Look at Supernova
NASA’s IXPE (Imaging X-ray Polarimetry Explorer) mission has taken a new observation of a #Supernova, RCW 86, seen here in an image released on March 24, 2026.
This observation helps fill in a fuller picture of what other telescopes have seen.
