NASA Scientists Successful In Finding the Secret behind the Supernovae Creation

The NASA scientists had a set a new mission to discover the environment that creates supernovae.

The scientists asserted that supernovae have helped them so far to understand the universe, but till now no information has been obtained to know how these valuable elements are created.

Stefan Immler, an Astrophysicist at NASA's Goddard Space Flight Center said, “For all their importance, it's a bit embarrassing for astronomers that we don't know fundamental facts about the environs of these supernovae”.

Till now the only facts that are known to the scientists about the supernovae are that they are formed when gas flows into a white dwarf that is similar to Sun in mass and equivalent to Earth in its volume. White dwarf is a small star. The gas that flows into it increases its mass and thus it explodes after the threshold has been achieved.

The explosion leads to the release of consistent, visible energy for weeks. This in turn helps the scientists to measure the distance of the exploding star from the Earth.

However, now to understand more about the supernovae, the scientists used their Swift Satellite. This satellite is orbiting the Earth and is sending back useful information from the Type Ia supernovae, which is the closest to the Earth since 1986.

The information included X-ray and ultraviolet data, which has further cleared the doubts of the scientists regarding the events leading up to the star’s explosion.

It has been concluded from two different studies that it is not always possible that a giant star is present when supernova occurs; hence the white dwarf is obtaining the energy from another white dwarf or some other small or young star, which might be similar to Sun. in case of Type Ia supernova even, two white dwarfs merged to provide the energy.

The X-ray study is expected to be published by April 1 and the ultraviolet by April 10.

Austin tech leaders unveil ‘RideAustin’ non-profit ride-hailing service

In an announcement made on Monday, tech leaders in Austin unveiled a non-profit car-for-hire service -- called RideAustin -- backed by local donations. The new service is an alternative created by Austin-based engineers to Uber and Lyft ride-hailing services which have been ousted from the city after a contentious regulation scuffle.
