A rare glimpse of a star before it went supernova defies expectations

Posted by in category: alien life

A rare glimpse of a star before it exploded in a fiery supernova looks nothing like astronomers expected, a new study suggests.

Images from the Hubble Space Telescope reveal that a relatively cool, puffy star ended its life in a hydrogen-free supernova. Until now, supernovas without hydrogen were thought to originate only from extremely hot, compact stars.

The discovery “is a very important test case for stellar evolution,” says Sung-Chul Yoon, an astrophysicist at Seoul National University in South Korea, who was not involved in the work. Theorists have some ideas about how massive stars behave right before they blow up, but such hefty stars are scant in the local universe and many are nowhere near ready to go supernova, Yoon says. Retroactively identifying the star responsible for a supernova provides an opportunity to test scenarios of how stars evolve right before exploding.

Mushrooms on Mars: Do These Images Show Proof of Life on Mars?

Posted by in category: alien life

Scientists believe these photos show mushrooms on mars—and proof of life.


Could there be mushrooms on Mars? In a new paper, an international team of scientists from countries including the U.S., France, and China have gathered and compared photographic evidence they claim shows fungus-like objects growing on the Red Planet.

SpaceX ready to break another rocket reuse record with launch early Sunday

Posted by in categories: internet, satellites

A Falcon 9 rocket and 60 more Starlink internet satellites set for launch early Sunday at Cape Canaveral will mark the first time SpaceX has flown a first stage 10 times, reaching a milestone that the company once said could be a limit for reusing boosters. Now SpaceX plans to keep flying reused rockets on Starlink missions until one fails.

The mission Sunday is set for liftoff at 2:42 a.m. EDT (0642 GMT) from pad 40 at Cape Canaveral Space Force Station, Florida. Nine kerosene-burning Merlin 1D engines will power the Falcon 9 rocket northeast from Florida’s Space Coast, following a trail blazed by 26 previous dedicated Starlink missions.

There is an 80 percent chance of good weather for launch at Cape Canaveral, according to the 45th Weather Squadron at Patrick Space Force Base. There is also a good chance of favorable upper level winds and acceptable conditions in the Falcon 9 booster’s downrange recovery area in the Atlantic Ocean.

New “Key-Hole Surgery” Technique to Extract Metals From the Earth – Could Revolutionize the Future of Mining

Posted by in categories: biotech/medical, materials

A team of international researchers, including Dr. Rich Crane from the Camborne School of Mines, University of Exeter, have developed a new method to extract metals, such as copper, from their parent ore body.

The research team has provided a proof of concept for the application of an electric field to control the movement of an acid within a low permeability copper-bearing ore deposit to selectively dissolve and recover the metal in situ.

This is in contrast to the conventional approach for the mining of such deposits where the material must be physically excavated, which requires removal of both overburden and any impurities within the ore (known as gangue material).
