Webb peers into a massive galaxy cluster and finds a stunning menagerie of gravitationally lensed background galaxies from earlier epochs, again revealing the power of the telescope’s infrared vision.
A family portrait of Jupiter and three of its Galilean moons shows off the skills of two “citizen scientists” using public domain imagery from NASA’s Juno orbiter.
The Euclid space telescope has reached its operational orbit and initial test images show the probe’s two instruments are operating in fine fashion as they’re fine tuned for science observations.
Flight controllers mistakenly commanded Voyager 2 to point slightly away from Earth, interrupting communications, but the spacecraft is expected to reset itself in October.
Astronomers have found what amounts to a two-faced white dwarf with one side dominated by hydrogen and the other by helium in what could be a transition from one phase to another.
Trojan planets – two worlds sharing the same orbit around their star – are possible in theory, but none have been found. Now, the ALMA radio telescope array may have done just that.
The Hubble Space Telescope searches for massive galactic clusters to learn more about gravitational lensing, the distortion and magnification of light from background, more distant bodies caused by a cluster’s enormous gravity.
ESO’s aptly named Extremely Large Telescope is now roughly halfway complete, with its dome quickly rising in Chile and the telescope coming together in Europe.
Data from Webb and Hubble combine to take viewers on a video tour from the present all the way back to 390 million years after the Big Bang and a never-before-seen early galaxy.
