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.
Amongst its embarrassment of deep-sky riches, mighty Cygnus, the Swan, hosts two famous stars, the dwarf nova variable star SS Cygni and the binary 61 Cygni.
Messier 14 (NGC 6402) is one of Ophiuchus’ seven Messier-tagged globular clusters, which are incredibly dense balls of stars that can provide striking viewing.
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.
NASA marks the first anniversary of Webb science observations with a spectacular look into a nearby stellar nursery where 50 young sun-like stars are lighting up their surroundings.
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.
