Astronomers using the Dark Energy Camera (DECam) on the Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory have discovered two rare Atira/Apohele asteroids, which have orbits completely interior to Earth’s orbit, and one Apollo-type asteroid that crosses Earth’s orbit. The latter is likely the largest Potentially Hazardous Asteroid (PHA) discovered in about eight years. An artist’s impression of an asteroid that orbits...

This image, taken by the OmegaCAM camera at ESO’s VLT Survey Telescope, shows a spectacular view of the orange and pink clouds that make up the Vela SNR. OmegaCAM can take images through several filters that let through light of different colors. In this particular image of the Vela SNR, four different filters were used, represented here by a combination of magenta, blue, green and red.

This image shows two member galaxies, PGC 36733 (left) and PGC 36723 (right), in the Wild’s Triplet. The galaxies are a mix of pale blue and yellow in color, crossed by strands of dark red dust. A long, faint streak of pale blue joins them, extending from an arm of one galaxy and crossing the field diagonally. A small spiral galaxy, orange in color, is visible edge-on, left of PGC 36723.
