2MASS J20395358+4222505 is an obscured early B supergiant near the massive OB star association Cyg OB2. Despite its bright infrared magnitude (Ks= 5.82) it has...
All chemical elements in the Universe (except for H and most of the He) have been made in stellar interiors. But among those elements, the ones that allowed to...
The standard cosmological model states that massive galaxies contain a large fraction of dark matter. Dark matter is a transparent substance that does not...
The role of the Sagittarius dwarf galaxy in the evolution of our Galaxy
The European Space Agency's Gaia mission is revolutionising our understanding on how the Milky Way, the spiral galaxy we inhabit, has formed and evolved. Gaia...
The star formation rate evolution of low-mass galaxies as seen by OTELO
We present the analysis of a sample of Halpha, Hbeta and [OII] emission line galaxies from the OTELO survey, with masses typically below log(M */Msun) = 9.4 and...
The surface of asteroid Bennu: dark, rough and dense with boulders
Between August and December 2018, during the Approach and Preliminary Survey phases of the NASA OSIRIS-REx mission, a series of images and spectra of the...
The synchronized dance of the Magellanic Clouds star formation history
According to the current theories of galaxy formation, these generally form as small entities that grow through fusion, collision and accretion, eventually...
Tidally trapped pulsations in a close binary star system
It has long been suspected that tidal forces in close binary stars could modify the orientation of the pulsation axis of the constituent stars. Such stars have...
When the Sun is observed in X-ray or extreme ultraviolet wavelengths, hundreds of bright and compact structures with a rounded shape and sizes similar to that...
