Scientists spot a cosmic vampire


READ MORE

Luckily, we had telescopes in place to spot it.


From Earth, the explosion shone a brilliant blue, an indication the supernova reached billions of degrees in temperature.


“It is,” said Dr Brad Tucker, “a very, very massive event”.


Dr Tucker, an astronomer at the Australian National University, was part of a team of 130 international scientists who have spent months studying data and images from the star’s explosion, captured by telescopes around the world.


Supernovas, among the most powerful explosions in the galaxy, are exceedingly rare. Astronomers knew they could be caused when two white dwarfs – ancient superheavy stars that have run out of fuel and been compressed by gravity to about the size of our planet – slammed into each other.

Non-surgical rhinoplasty is on the rise, but not everyone is convinced

READ MORE I can remember about 10 years ago going to a Cosmetex cosmetic surgery conference in Sydney where a doctor gave a demonstration, injecting the filler Restylane (a form of hyaluronic acid ) into a hooked nose; the de-bumping results were really impressive, and it only took 15 minutes. Since then there has been a steady rise in the use of nose fillers: also referred to as the non surgical nose job. Now, I have had the full-blown open rhinoplasty surgical version so am keen to drill down (pardon the pun) and find out more about the ins and outs of the “liquid nose job”. “Liquid nose jobs” are on the rise. Photo: Shutterstock Shereene Idriss a clinical instructor in dermatology at the Icahn School of Medicine at Mount Sinai, and a cosmetic dermatologist at Union Square Laser Dermatology in New York City, has lots to say on her #pillowtalkderm about the pitfalls of the liquid nose job. “Liquid rhinoplasty, as seen on social media, appears to be t...

READ MORE Tens of thousands of demonstrators, baking in the heat and boiling mad at US immigration policy, marched across the country Saturday to protest the separation of families under President Donald Trump’s hardline agenda. Directly across from the White House, demonstrators filled Lafayette Square park in an atmosphere of both indignation and sadness, before marching toward the Capitol. “We don’t believe in borders, we don’t believe in walls,” Sebastian Medina-Tayac, of the Piscataway Indian Nation, declared in English and Spanish at the start of the rally dubbed “Families Belong Together.” Loudspeakers broadcast the cries of a child split from its relatives, as a Brazilian mother told of being separated from her own son. “I missed nine months of his life and it should never have happened,” said the woman, Jocelyn, whose case dates from before the practice of separating families intensified in May. “Shame! Shame!” ...
