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.

ALMA spots exoplanet and possible sibling sharing same orbit

19 July 2023 Astronomy Now

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.

Hubble probes merging galaxy clusters combining to form powerful gravitational lenses

19 July 2023 Astronomy Now

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.
