Rare space object captured by Hubble The Hubble Space Telescope has snapped a picture of a rare phenomenon: bright blue jets of gas blasting out from a dust cloud. Known as a Herbig-Haro object, this image shows the genesis of a star system. In the centre, a baby star is being born, spinning as it … Continue reading You may have missed…

Spinning star hurtling out of the Milky Way

Astronomers have discovered that the runaway star LP 40−365 is not only catapulting out of our galaxy, but it’s spinning as it goes. “This star is moving so fast that it’s almost certainly leaving the galaxy…[it’s] moving almost two million miles an hour,” says JJ Hermes from Boston University, co-author of a new paper published … Continue reading Spinning star hurtling out of the Milky Way

Teardrop star reveals hidden supernova doom

Astronomers have spotted a teardrop star that suggests two dwarfs are spiralling towards supernova doom. The team, led by Ingrid Pelisoli of the University of Warwick in the UK, recently found the stars, which are 1,500 light years away; one is a hot subdwarf and the other a white dwarf that orbit each other closely … Continue reading Teardrop star reveals hidden supernova doom

Colossal cataclysm may explain mystery star

Australian-led researchers believe they have found evidence for a new type of stellar explosion – a magneto-rotational hypernova – that may solve the mystery of why some of the earliest stars in the universe contain more heavy metals than others. More than 13 billion years ago, the first generations of stars were made almost entirely … Continue reading Colossal cataclysm may explain mystery star

New type of supernova spotted

An international team of astronomers has uncovered the first convincing evidence for a new type of stellar explosion: an electron capture supernova. For two years, the team collected detailed data on the supernova 2018zd, which astronomers spotted in March 2018, just hours after it exploded 31 million light years away in the galaxy NGC 2146. … Continue reading New type of supernova spotted

A flash of inspiration

Astrophysicists have spotted a spectacular flash of ultraviolet light accompanying a white dwarf explosion. It’s only the second time such a rare type of supernova has been seen, they say, and may help explain how white dwarfs explode. The flash “is telling us something very specific”, says Adam Miller from Northwestern University, US, the lead … Continue reading A flash of inspiration
