Astronomers saw in space is born the twin of the Earth


Emerging exoplanets, which in the future promises to be very similar to Earth, discovered by experts from the European southern Observatory, working with radio telescopes in the ALMA complex. Protoplanetary disk, which is a potential double planet, according to scientists, is located in the constellation Hydra at a distance of about 175 light-years — that is, by the standards of space, very close.

Watching the star TW Hydra, which, as it was earlier known, is very similar to the Sun, astronomers have discovered the lumen, indicating the formation of a new cosmic body at approximately the same distance from it at which the Earth rotates about the Sun. It is highly likely that in the future this will be similar exoplanet to Earth, according to representatives of the European southern Observatory.

The age of the TW Hydra, scientists estimate that is about 10 million years, so she is much younger than the Sun. In this regard, scientists hope that observing the formation of exoplanets, they will be able to study a similar process of formation of the Earth orbiting the Sun in the distant past. Experts note that the protoplanetary disk TW Hydra is the closest to the Earth is known, which significantly simplifies the monitoring of this object.

While experts do not exclude the possibility that the emerging exoplanets will be much more massive than the Earth. To find out, will need additional monitoring.

Starry sky often helps astronomers to peek into the hypothetical past or the potential future of the Solar system. For example, observations of star WD 1145+017 in the constellation of Virgo, which lasted for seven months, has allowed scientists a better idea of what awaits the Earth and other planets in a few billion years when the Sun expands into a red giant and will start to destroy the surrounding space bodies. And the study of a yellow dwarf star called Kappa Keith recently helped to clarify the role of the Earth’s magnetic field in the formation of life on it.

Recently experts from MIPT and the RAS Institute of space research, proposed a new way to observe exoplanets, which may well be “twins” of the Earth. To do this, scientists propose to “fix” the light from distant stars.
