The place where stars are born

In interstellar molecular clouds, large molecules can form despite the non-ideal conditions prevailing there
Image 1. Topography and SAR image of the research area on Venus. Color indicates altitudes, measured relative to the planet's mean radius from Magellan's reticulated altitude data. The X and Y axes represent geographic longitude and latitude of the planet. From the study.

A new analysis of data from the XNUMXs has proven that volcanoes are still erupting on Venus today

The article "Surface changes observed on a volcano in Venus during the Magellan mission" describes the analysis of the observations in which surface changes were discovered on the Sif Mons volcano during the Magellan spacecraft mission in 1991-1994
Iconography showing the habitable zone around the planet Teegarden in two conservative and optimistic scenarios, compared to our solar system and other planets discovered in their star's habitable zone. The scale is normalized to the size of our solar system. In practice the planets Teegarden b and Teegarden c are much closer to their sun. Illustration: C. Harman

A new catalog based on Kepler space telescope data has found 219 additional planet candidates. Of these, 10 Earth-like planets orbit their star in the "seat zone," one that is at a distance that allows liquid water to exist on the surface. Illustration: NASA/JPL-Caltech.

The Kepler space telescope found 219 more planets and revealed a clear gap between terrestrial planets and mini-Neptunes

A diagram showing all the round bodies in the solar system with a diameter of less than 10,000 km. If the researchers' proposal is accepted, at least 110 bodies in the solar system will be defined as planets. Source: Montage by Emily Lakdawalla. Data from NASA / JPL, JHUAPL/SwRI , SSI, and UCLA / MPS / DLR / IDA, processed by Gordan Ugarkovic, Ted Stryk, Bjorn Jonsson, Roman Tkachenko, and Emily Lakdawalla.
