Astronomers using the NASA/ESA Hubble Space Telescope have imaged a Jupiter-sized, still-forming planet around the orange dwarf star PDS 70.

This is the first time that an exoplanet has been directly imaged in the ultraviolet (UV).

PDS 70 is a K7-type pre-main sequence star located 370 light-years away in the constellation of Centaurus.

Also known as V* V1032 Cen and IRAS 14050-4109, the star is only 5.4 million years old.

It hosts two actively forming planets, PDS 70b and c, and a huge circumstellar disk of dust and gas in which a large region from 20 to 40 AU is cleared of dust.

PDS 70b is located within the disk gap at a distance of about 21 AU from the star, similar to the orbit of Uranus in our Solar System.

PDS 70c is located near the outer edge of the disk gap at 34.5 AU from the star, similar to Neptune’s distance from our Sun.

This Hubble image shows the young exoplanet PDS 70b.

According to the team, PDS 70b has already bulked up to five times the mass of Jupiter over a period of 5.4 million years.

Zooming in on the strange galaxy Centaurus A

This video zoom sequence starts with a broad view of the Milky Way.

We close in on a region not far from the plane of a the galaxy and can soon see a strange fuzz with a dark band across it.

This is the famous peculiar radio galaxy Centaurus A.
