During the thirty-sixth close approach of the gas giant planet Jupiter by NASA’s Juno spacecraft, it snapped a raw image of tumultuous clouds in the South Temperate Belt.
When measuring the Hubble constant by mapping the properties of the cosmic microwave background radiation to the standard model of cosmology, astronomers get a value of about 69 kilometres per second per megaparsec.
In 2014, a quite remarkable collage was released by scientists who used NASA’s Spitzer Space Telescope to image the entirety of the Milky Way in infrared light.
NASA’s Juno probe captures a stunning image of Ganymede’s shadow moving across Jupiter’s cloud tops, providing a unique perspective on an event familiar to amateur astronomers.
NASA’s Perseverance Mars rover’s Mastcam-Z camera has captured Phobos, the larger of Mars’ two small moons (27 x 22 x 18 kilometres), as it transited the Sun’s disc on 2 April
The Advanced Camera for Surveys aboard the Hubble Space Telescope has provided many of the observatory’s most spectacular – and scientifically valuable – images. NASA and ESA present samples of its work in a 20th anniversary collection.
Two galaxies passing through one another in a head-on collision generate a burst of star formation in an intriguing triangular shape caused by ongoing gravitational interactions.
Hubble captures a dramatic view of two galaxies, both with active galactic nuclei, interacting in a close encounter that is pulling gas, dust and entire star systems from one toward the other.
Taking a second look with a more powerful camera, Hubble reveals thousands of emission nebulae in an oddball irregular dwarf galaxy 17 million light years from Earth
