The Backyard Worlds: Planet 9 project re-launches this week, with a call to volunteer citizen scientists to join the search for cold worlds near the Sun.

Astronomers using adaptive optics on the 8-meter Gemini North telescope have resolved, for the first time in near-infrared light, a giant elliptical galaxy with a young radio jet down to unprecedented scales.
National Optical Astronomy Observatory (NOAO), along with the Association of Universities for Research in Astronomy (AURA), are pleased to announce a transition plan for NOAO leadership through the rest of this year, following the departure of David Silva January 25.
An unusual supernova studied by multiple telescopes, including the SOAR telescope and other telescopes at the National Science Foundation’s (NSF) Cerro Tololo Inter-American Observatory (CTIO) and NSF’s Kitt Peak National Observatory (KPNO), is thought to herald the birth of a new black hole or neutron star, caught at the exact moment of its creation.
Observations from Gemini Observatory identify a key fingerprint of an extremely distant quasar, allowing astronomers to sample light emitted from the dawn of time. Astronomers happened upon this deep glimpse into space and time thanks to an unremarkable foreground galaxy acting as a gravitational lens, which magnified the quasar’s ancient light.
On the night of 9 January 2019, the V. M. Blanco 4-meter telescope at the National Science Foundation’s (NSF) Cerro Tololo Inter-American Observatory (CTIO), high in the mountains of Chile, will close the camera’s shutter on the final image from the Dark Energy Survey (DES) – a survey that has mapped 5,000 square degrees of the heavens, almost one-quarter of the southern sky.
NASA’s Hubble Space Telescope has produced this stunningly detailed portrait of the Triangulum galaxy (M33), displaying a full spiral face aglow with the light of nearly 25 million individually resolved stars. It is the largest high-resolution mosaic image of Triangulum ever assembled, composed of 54 Hubble fields of view spanning an area more than 19,000 light-years across.
It is with great sadness that AURA recognizes the passing of Riccardo Giacconi. Giacconi was a highly accomplished astrophysicist and the first permanent Director of the Space Telescope Science Institute.
The figure shows the variation of the meridional flow as slices of time and depth for eight latitudes from mid-latitudes (top) to the equator (bottom) averaged over both hemispheres. The mean value has been subtracted to highlight the variation with time. The band of faster-than-average (poleward) meridional flow (yellow-red) is the most noticeable feature moving […]
This visualization of a spectacular spiral galaxy, called the Whirlpool Galaxy, appears in the “Deep Field” film. Based on a 90-megapixel image from the Hubble Space Telescope, the visualization sequence sweeps viewers past the swirling structure of dark dust lanes, yellowish older stars, bluish younger stars, and vibrant red star-forming regions.
