Helix nebula, infrared Spitzer image Featured Print

Helix nebula, infrared Spitzer image

Helix nebula (NGC 7293), infrared Spitzer Space Telescope image. This is a planetary nebula, a series of shells of gas cast off by a dying star. The ejection of the star's outer layers exposes its hot core, whose radiation ionises the shells, causing them to glow. This image was taken at wavelengths of varying energy: high (blue), medium (green) and low (red). The gas in the central regions has been ionised more than the outer gas, which is shielded from the stellar core. The most highly ionised areas (cometary heads) are round the edge of the central void. Foreground and background stars are blue. The Helix nebula is 650 light years from Earth, in the constellation of Aquarius. Image data obtained by the IRAC sensor in October 2004


Antares/Rho Ophiuchi region Featured Print

Antares/Rho Ophiuchi region

Antares/Rho Ophiuchi region, optical image. This colourful region lies in the constellations Scorpius and Ophiuchus. The blue area at upper right is the triplet star Rho Ophiuchi, embedded in the reflection nebula IC 4604. This nebula does not emit light of its own, but reflects light from the star and appears blue due to blue light being scattered more than red light. The large orb at lower left is the supergiant star Antares (Alpha Scorpii), next to the yellow emission nebula IC 4606. This nebula emits light due to its gas and dust clouds being ionised by radiation from the stars. At right is the star Sigma Scorpii with its pink emission nebula Ced 130, and at lower right is the dense globular star cluster M4 (NGC 6121)


Trifid Nebula M20, Hubble image Featured Print

Trifid Nebula M20, Hubble image

Trifid Nebula (M20, NGC 6514). Combined images from the Subaru Telescope and Hubble Space telescope of the Trifid Nebula M20. The Trifid Nebula lies around 9000 light years from Earth in the constellation Sagittarius. Part of this nebula (cloud of gas and dust) glows red due to the ionisation of the hydrogen gas by the hot and bright stars born at its centre. This is called an emission nebula. The M20 emission nebula is partially obscured by a dark nebula (B85) in front of it, causing the three-lobed appearance. The M20 nebula is not all ionised, with parts of it reflecting starlight as a blue colour
