beta Pictoris b
الشرح: This composite of two images shows the planet beta Pictoris b and a disk of material both of which orbit the young star beta Pictoris. Both are taken in infrared light. The inner image was one of the first pictures taken of a planet around another star (an exoplanet). This image was made using a technique called adaptive optics which removes the blurring effect of the Earth's atmosphere that spreads out a star's light. The star's light is then concentrated tightly enough that it can be hidden behind a blocking circle (shown here in black) called a coronagraph. The ripples around this are artifacts of the imaging process. Beta Pictoris b, a gas giant planet about twelve times the mass of Jupiter, appears as a dot above and to the left of the black circle.
The outer image shows the thermal emission from the warm disk of material surrounding the young star beta Pictoris. As we are viewing this disk edge-on it appears as a line. This disk of gas and dust provided the material to form beta Pictoris b.

The planet PDS 70b inside a protoplanetary disk
الشرح: An image of the planet PDS 70b. The young star PDS 70b has a protoplanetary disk surrounding it. Disks like these contains gas, fine sandy particles that astronomers refer to as dust and also larger bodies ranging from objects the size of pebbles to protoplanets (planets that are still forming).
This image was taken in infrared light using adaptive optics. Adaptive optics is a technique that uses flexible mirrors and computer analysis to remove the blurring effect of the Earth's atmosphere. This allows astronomers to search regions close to stars like PDS 70 that would otherwise be swamped by light from the star spread out by the Earth's atmosphere. In the center is a black circle. This is caused by a coronograph, a small circle that blocks out light from the parent star. This is surrounded by a bright oval, infrared light emitted from the material in the protoplanetary disk. To the right of the black circle covering the star is a bright dot. This is PDS 70b, a giant planet that is still forming .
