A meteor seen over the South Pacific, off the northern coast of Papua New Guinea, in 2014 likely came from interstellar space, according to new research from Harvard University. If confirmed, the object will be only the second known visitor from beyond the Solar System; the other is ‘Oumuamua, a fast moving comet of extrasolar origin discovered in October 2017. A fireball.

This image of Messier 62 is a composite of separate exposures acquired by Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) instruments. It is based on data obtained through four filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This infrared image was recorded by Subaru Telescope’s COMICS instrument. Sinclair et al used red, blue and yellow to infuse this image; regions of the atmosphere that are more yellow and red indicate the hotter areas. This highlights the auroral heating that occurs at Jupiter’s poles, where energy from the solar wind and magnetosphere are deposited. This image was captured on January 12, 2017.

This artist’s impression shows a view of the surface of Proxima b orbiting Proxima Centauri. Alpha Centauri AB also appears in the image to the upper-right of Proxima itself. Proxima b is a little more massive than the Earth and orbits in the habitable zone around its star, where the temperature is suitable for liquid water to exist on its surface. Image credit: M. Kornmesser / ESO.

The EHT Collaboration unveiled the first direct visual evidence of the supermassive black hole in the center of the elliptical galaxy Messier 87 and its shadow. The shadow of a black hole seen here is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. The black hole’s boundary -- the event horizon from which the EHT takes its name -- is around 2.5 times smaller than the shadow it casts and measures just under 25 billion miles (40 billion km) across.

This is a composite picture showing images of storms on Neptune from Hubble (left) and Voyager 2 (right). The Hubble image shows a new dark storm (top center). In the Voyager image, a storm known as the Great Dark Spot is seen at the center. It is about 8,000 miles by 4,100 miles (13,000 km by 6,600 km) in size -- as large along its longer dimension as the Earth. The white clouds seen hovering in the vicinity of the storms are higher in altitude than the dark material. Image credit: NASA / ESA / Hubble / GSFC / JPL.
