Caption: 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.

Caption: This image shows the disk around the young star TW Hydrae. This star is only about 10 million years old, young enough that planets are still forming in a disk of gas and dust around it. This image was created using an array of submillimetre telescopes, each of which looks like a satellite dish. The signals from these telescopes were combined by a central processing computer to make this image. The lighter and darker patches show areas of the disk where there is more or less dust respectively. The dark rings and bright rings are evidence that the dust in the disk has been shepherded into some orbits and away from others. This is likely because there is one or more planets that are still forming hidden in the disk. The whole image shows the disk around TW Hydrae out to a distance of about 70 astronomical units frm the central star. The two outer dark rings are separated from the central star by approximately the average distance between the Sun and Uranus and the average distance between the Sun and Pluto. The inner central hole appears to have been carved out by a planet orbiting TW Hydrae at a distance similar to the distance between the Earth and the Sun.

Caption: The constellation Pictor with its bright stars and surrounding constellations. Pictor is surrounded by (going clockwise from the top): Columba, Caelum, Dorado, Volans, Carina and Puppis. Pictor is notable for its second brightest star, Beta Pictoris. This young star hosts a large disk of dusty material left over from the planet formation process along with two planets, one of which Beta Pictoris b was one of the first planets to be directly imaged by astronomers. Pictor is a southern constellation and thus the whole constellation is visible at some point in the year throughout the southern hemisphere. The whole constellation is also visible from some equatorial regions of the northern hemisphere with parts of the constellation visible to the remaining northern equatorial regions and some northern hemisphere temperate zones. Pictor is best viewed in the northern hemisphere winter and southern hemisphere summer. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. Neither the constellation boundaries, nor the lines joining the stars appear on the sky.
