Magnetars are a type of neutron star, an incredibly dense object mainly made up of tightly packed neutron, which forms from the collapsed core of a massive star during a supernova. What sets magnetars apart from other neutron stars is that they also have the most powerful known magnetic fields in the universe.

For the first time, astronomers witnessed the birth of a 'magnetar'
Science Space Deep Space Black Holes For the first time, astronomers witnessed the birth of a'magnetar' These fast spinning, magnetic neutron stars may power some of the brightest supernovae in the cosmos. Artist's conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets of charged particles emanate from the magnetar along its rotation axis. Breakthroughs, discoveries, and DIY tips sent six days a week. In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory.

Two neutron stars may have formed the first known 'superkilonova'
Science Space Deep Space Space Telescope Two neutron stars may have formed the first known'superkilonova' The historic explosion was 1.3 billion light-years away from Earth. Breakthroughs, discoveries, and DIY tips sent every weekday. A double blast of dying stars may be the first observed case of a long-hypothesized, never proven "superkilonova." Although astronomers are still searching for concrete answers, a study published in may detail the historic explosion about 1.3 billion light-years from Earth. Most of the universe's massive stars end their lives in a blaze of glory as supernovae, but that's not always the case.
Massive newborn star is firing two plasma jets at once
Breakthroughs, discoveries, and DIY tips sent every weekday. A newborn star 15,000 light-years from Earth is fascinating astronomers with its dual blasts of superheated plasma jets . The rare sight captured in stunning detail by the James Webb Space Telescope (JWST) isn't only a display of cosmic forces. It's helping solve a decades' long debate about the origins of massive stellar objects. Located at the edge of the Milky Way galaxy inside a nebula known as Sharpless 2-284 (Sh2-284), the young protostar is already upwards of 10 times the mass of our sun .
Pair of exploding stars baffle astronomers
New images of two novae are'like going from a grainy black-and-white photo to high-definition video.' Breakthroughs, discoveries, and DIY tips sent every weekday. The recent deaths of two white dwarf stars are challenging our understanding of both novae and the powerful physics underlying star death. According to astronomer John Monnier, the initial analysis of these often dramatic novae offers an "extraordinary leap forward" for the field. "The fact that we can now watch stars explode and immediately see the structure of the material being blasted into space is remarkable," said the University of Michigan astronomer and a co-author of a study published on December 5 in the journal .

Newborn supernova spotted only hours after its explosive birth
Astronomers illustrated supernova SN 2024ggi in all of its gassy glory. This artist's impression shows a star going supernova. About 22 million light-years away the supernova, SN 2024ggi, exploded in the galaxy NGC 3621. Breakthroughs, discoveries, and DIY tips sent every weekday. According to their study recently published in the journal, their stellar accomplishment thanks to quick thinking and intense geometrical calculations is already providing clues to longstanding questions about some of the universe's most impressive and powerful events .

A star unleashed a planet-destroying flare
It's the first coronal mass ejection seen outside our sun. Breakthroughs, discoveries, and DIY tips sent every weekday. Skygazers can once again thank the sun for the latest round of Northern Lights that recently danced above much of the United States. Also known as the aurora borealis in the north, (or aurora australis in the Southern Hemisphere) these night sky events get their start on the sun's surface after coronal mass ejections (CMEs) spew ionized clouds of high energy particles towards Earth. The radiation then interacts with the planet's magnetosphere and generates the vivid colors in Earth's atmosphere-as well as the occasional electrical grid and satellite array headache .

Scientists predict the universe will end in 'big crunch'
Science Space Deep Space Scientists predict the universe will end in'big crunch' Starts with a bang, ends with a crunch. Breakthroughs, discoveries, and DIY tips sent every weekday. Our vast universe might not be infinitely expanding after all. Some newly reviewed dark energy data may contradict the theory first posed in 1922 by the astronomer Alexander Friedmann. According to a study recently published in the, the cosmos will actually conclude with a "big crunch."
A black hole ripped apart a supernova
Breakthroughs, discoveries, and DIY tips sent every weekday. Astronomers taking a closer look at a cosmic showdown have spotted a rare, mindbending event 730 million light-years from Earth. After reviewing a massive stellar explosion, researchers believe they spotted a never-before-seen type of supernova that involves a nearby black hole. According to their study published August 13 in the Astrophysical Journal, it may be the first of many other, similar discoveries. Supernovae are some of the most violent moments in the universe.
