'Cloudy with a Chance of Dust'

(Image credit: ESO)

Thursday, December 12, 2019: Thick clouds of interstellar dust and gas permeate the star forming region RCW 36, also known as Gum 20, in this deep-space image from the European Southern Observatory's Very Large Telescope (VLT) in Chile. Located about 2,300 light-years away from Earth in the constellation of Vela (the sails), RCW 36 is part of a much larger star formation complex, known as the Vela Molecular Ridge. Astronomers used an instrument on VLT called the Focal Reducer and low dispersion Spectrograph (FORS) to capture this image of RCW 36, which is in some parts so thick with dust and gas that background light cannot pass through. These dark regions are the richest with star formation. — Hanneke Weitering

Algae Blooms Seen from Space

Monday, December 16, 2019: The interstellar comet Borisov appears to come face-to-face with a distant spiral galaxy in this image from the Hubble Space Telescope. Hubble captured this image on Dec. 12, as the interstellar comet was racing through the inner solar system. At the time, the object was about 260 million miles (420 million kilometers) from Earth, while the unnamed background galaxy (officially designated 2MASX J10500165-0152029), is nearly half a billion light-years away. The galaxy appears smudged because Hubble was tracking the motion of the comet, which was zooming through space at a speed of about 109,000 mph (175,000 km/h). — Hanneke Weitering

(Image credit: NASA GSFC)

Thursday, December 19, 2019: NASA scientists have spotted what looks like a candy cane-shaped cloud of glowing gas near the center of the Milky Way. The "candy cane" is about 190 light-years long and contains ionized gas that emits radio waves. Astronomers discovered it using an instrument known as the Goddard-IRAM Superconducting 2-Millimeter Observer, or GISMO, together with a radio telescope on Pico Veleta in Spain. You can see the full, annotated version of this image here. — Hanneke Weitering
