'Incredible milestone': Astronomers identify over 360 previous unknown exoplanets

Researchers for the first time have successfully observed a<a href="https://www.wionews.com/science/scientists-solve-mystery-behind-elusive-supernova-which-birthed-crab-nebula-394698"> supernova</a> in its initial phase while trawling through data from Nasa’s Kepler space telescope.

The telescope had recorded the event in 2017 as astrophysicists noted the light burst from a supernova as the star exploded.

The study was published in monthly notices of the royal astronomical society. The Kepler space telescope which recorded the celestial event is no longer in use. It reportedly took photos of the same part of the sky for 40 days at a stretch while almost accidentally recording the remarkable phenomena.

The light from the supernova takes several weeks even months to fade. The phenomena has&nbsp;been recorded through ancient times.&nbsp;

The NASA telescope took pictures every half an hour allowing it to accurately take unique photos&nbsp;as the historic event unfolded without anyone noticing.&nbsp;The early explosion can be recorded only for a few days.

The supernova was recorded in real-time helping scientists to record the evolution of stars. Astromers say they now have a somewhat clearer picture of how stars collapse then earlier.

The supernova recorded by the Kepler telescope was a billion light-years away from the Earth.

The star was reportedly hundred times the size of the Sun.&nbsp;

The shock cooling light curve allows scientists to measure the light emitted by supernova over a period of time and it also gives information on its composition.

Reports say NASA's&nbsp;Transiting Exoplanet Survey Satellite (TESS) is likely to record more supernovae explosions as they occur.

Today in History: Bell recieves patent, Tyson youngest champion and more!

On Monday, June 19, NASA held a media briefing to announce the completed catalogue of exoplanets from the Kepler Mission.

The catalogue lists 4,034 exoplanet discoveries, including 219 new finds. Ten of these new worlds are close in size to the Earth and reside within their star&rsquo;s habitable zone, a location that would permit liquid water on the surface of an Earth-like world.

These ten join roughly 40 other worlds found by Kepler as possible candidates for Earth&rsquo;s twin. But is the prospect of another Earth really the Kepler legacy?

Teeming with planets

While planets had been discovered around other stars since the early 1990s, the launch of the Kepler Space Telescope in 2009 resulted in them being found in droves. As the numbers increased from tens to thousands of exoplanets, astronomers were able to identify types of planets and speculate on their frequency through our Galaxy; Kepler had given us the ability to do statistics.

Our Solar System suggests there are just two flavours of the planet: Terrestrial worlds like the Earth with rocky surfaces and thin atmospheres, and gas giants like Jupiter, whose solid cores are buried beneath thousands of kilometres of enveloping gases.

This neat, bimodal picture is taken to pieces in the Kepler Mission catalogue.

The catalogue contents reveal gas giants that orbit their star closer than Mercury, other worlds so hot their surface must be molten magma and planets around binary stars like Luke Skywalker&rsquo;s fictional home world of Tatooine in the film franchise Star Wars.

But perhaps the most mysterious entries are the so-called super-Earths.

How super, really?

Over two-thirds of the planets in the Kepler Mission Catalogue have radii of between 1.1 and four Earths, placing them between Earth and Neptune in size. These super-Earths are the most common planet discovered, yet our own Solar System has no analogue to tell us what such worlds might be like.

Are they terrestrial planets with rocky surfaces or mini gas giants with crushing atmospheric pressures? As interest has mounted in the prospect of finding a habitable planet, a key question is whether any of these worlds have a solid surface.

Our Solar System has only cold gas and ice giants and rocky terrestrial planets, but the Kepler Mission revealed many other planet types. (Others)
</div>
<a class="close-mark close-div" href="javascript:void(0)">&times;</a></div>

At the media briefing, NASA revealed that the Kepler Mission catalogue had produced a clue. A recent journal paper had spotted a split in the distribution of super-Earth planet sizes.

While planets with radii of around 1.3 Earths and 2.4 Earths are equally common, planets with sizes between 1.5 and two Earth radii are much harder to find. The astronomers speculate that this is the division between giant rocky planets and gaseous mini-Neptunes.

Although this strong divide in the super-Earth population has not previously been observed, its location agrees with the small number of planets we have bulk density measurements for. These density values suggest that planets larger than about 1.6 Earth radii have thick, Neptune-like atmospheres.

But while the Kepler Space Telescope can give us both sizes and locations for exoplanets, it cannot tell us anything about their past or the present surface environment. We need theories to explain the different planet types identified within the catalogue.

Explaining super-Earths

One possibility for the split in the super-Earth population is that the rocky planets have had their atmospheres stripped by radiation pouring from a star. Alternatively, the rocky worlds may have formed later from the gas-rich planet-forming disc that dispersed before the planets could accrue a thick atmosphere.

We meet a similar problem for the 50 planets found within the habitable zone. Knowing only their size and location is not enough to determine if their surfaces are similar to the Earth.

A difference in geology could create a very different atmosphere to our own, or the inability to create protective magnetic fields to shield the planet from sterilising stellar flares. The temperature may even be perfect for liquid water, but the planet entirely dry.

The space agency's Kepler Space Telescope, for the first time, has discovered an eighth planet in an alien solar system

NASA's Kepler Space Telescope, for the first time, has discovered an eighth planet in an alien solar system, the agency announced on Thursday. Similar to the sun, other stars can have large amounts of planets orbiting it. The star and its solar system were previously detected by the Kepler space telescope.

NASA said, "Machine learning is an approach to artificial intelligence, and demonstrates new ways of analysing Kepler data. "Kepler-90i is the smallest of the planets in that alien solar system.
