Ever ‘family’ photo shows two planets orbiting a young star

Ever ‘family’ photo shows two planets orbiting a young star

The ESO is now building the Extremely Large Telescope (ELT) which will have a 39 m main mirror and be the largest optical and near-infrared telescope in the world.

Astronomers detailed that the VLT's Spectro-Polarimetric High-Contrast Exoplanet Research (SPHERE) instrument uses its coronagraph to block the light emitted by faraway stars and, in turn, highlight the glow of distant exoplanets.

Astronomers have managed to capture a stunning photo of a sun-like star between two gaseous planets.

Now, using the same instrument, the team has captured another first, showing two exoplanets orbiting a star known as TYC 8998-760-1.

"This discovery is a snapshot of an natural environment that is very comparable to our solar program, but at a a lot before stage of its evolution", examine direct writer Alexander Bohn, a doctoral college student at Leiden University in the Netherlands, claimed in a assertion. Research published by Astrophysical Journal Letters, images by European Southern Observatory.

The direct imaging of more than two exoplanets has only ever been achieved twice before, but their parent stars were considerably different from our sun.

"Our team has now been able to take the first image of two gas giant companions that are orbiting a young, solar analogue", added Dr Maddalena Reggiani.

The striking image shows the star blazing bright yellow, with its two planets visible as pinpoints of light orange in the lower-left area of the frame.

The two gas giants orbit their host star at distances of 160 and about 320 times the Earth-Sun distance.

Additionally, the planets were found to be much heavier with the inner planet and outer planets being 14 times and 6 times the mass of Jupiter, respectively.

The ESO team was hunting for young stars when they found this particular one and its planets, according to the paper.

The star - now known as TYC 8998-760-1 and located in the constellation Musca, or Travel - is barely 17 million years old. To date, moreover, only a few dozen exoplanets have been photographed directly, and only two other multi-planet systems ... both around stars very different from the Sun.

So far, there are many more questions that remain about the planetary system. It will have the potential to test whether these planets formed at their current location and so far away from their stars or if they migrated from somewhere else. Observing other systems, especially in an immature state, offers us a glimpse at how these collections of planets appear and change over time. There may also be lower-mass planets in this solar system we can not now detect - maybe even some primordial Earth-like planets.

The ESO captured its photograph through the aptly-named Very Large Telescope (VLT), which can look across vast distances in space. And on Cerro Armazones, close to Paranal, ESO is building the 39-metre Extremely Large Telescope, the ELT, which will become "the world's biggest eye on the sky".
