NASA discovers ‘Exocomets’ reaching for young stars


Interstellar forecast for a nearby star to Earth have shown dipping comets into the stellar.  NASA’s Hubble Space Telescope has recently discovered Exocomets dipping onto the star HD 172555, which is a young 23 million years old star and dwell approx 95 light-years from Earth. Exocomets are gradually approaching toward this star. This youthful star may even get destroyed.

The Exocomets resides outside our solar system. They were never directly seen around the star celestials. However, their presence was discovered by detecting different types of gas that surround these stars and our solar system. And it is most likely to get the vaporized remnants of their icy nuclei.

The Hubble Space Telescope of NASA is a project of international cooperation between NASA and the European Space Agency (ESA). NASA Goddard centre manages the Hubble Space Telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts all the research and operations related to Hubble science operations. The project was set up to study the fundamental properties of our solar system and other celestial bodies.

HD 172555 represents the third extra-solar system. All of the systems in this region are young and are under 40 million years old. The unwanted presence of these Exocomets provides a circumstantial proof that a “gravitational stirring” by an unseen Jupiter-size planet has been seen. Here the Exocomets are deflected by its gravity and are thrown into the young star region. This rare phenomenon has also provided new insights into the past and present movements of comets in our solar system. It is myth mechanism where it is believed that these Exocomets can transport water to Earth and the other inner planets of our solar system.

The star that is targeted by the Exocomets is a part of the Beta Pictoris Moving Group, a collection of stars. It is the second group member of the same nursery of stars. Beta Pictoris, the name of the group where this star belongs to, is also experiencing some Exocomets travelling too close towards it. A young gas-giant planet has already been observed in that star’s vast debris disk.

This new discovery has made the stellar group important to study and research on because it is the closest collection of youthful stars to Earth. More than 38 percent of the more gigantic stars in the Beta Pictoris stellar Moving Group either have a directly imaged planet, such as 51 Eridani b in the 51 Eridani system or dipping in star-grazing bodies. In case of Beta Pictoris Stellar, both types of objects are seen.
