The Russian-European probe “ExoMars-TGO” did not detect even minimal traces of methane and two other hydrocarbons emitted by representatives of terrestrial life in the atmosphere of Mars.
The Event Horizon Telescope has obtained the most detailed image of relativistic jets erupting from the core of the Centaurus A radio galaxy. It turned out that the structure of the jets closely resembles the jet in the active galaxy M87 on a scale of up to five hundred gravitational radii of a black hole.
For the first time, astronomers have reliably registered the presence of a dusty Moon-forming disc around a protoplanet in an exoplanetary system. This was done thanks to the ALMA radio telescope, which observed the system of the young star PDS 70.
The Perseverance rover successfully drilled its first hole in the Martian surface, but subsequent analysis showed that the sampling tube did not grab any of the intended Martian soil.
Planetary scientists have proposed a possible explanation for the nature of Venusian phosphine without involving the activity of microorganisms. The emergence of this potential biomarker is assumed to be responsible for plume volcanism, which is still active on Venus.
