Tylos and its impetuous atmosphere – Media INAF

Tylos (or Wasp-121b) is a gas giant located about 900 light-years away in the constellation of Puppis (The Puppis). Using the ESPRESSO instrument on ESO’s Very Large Telescope, it has been possible to reconstruct its atmosphere in three dimensions for the first time on an exoplanet. It was discovered that it is divided into three layers, with iron winds in the lower part, followed by a very fast jet of sodium and finally an upper layer of hydrogen winds. This type of climate has never been observed before on any planet. Credits: ESO/M. Kornmesser

Star cluster reveals its colours in stunning 80-million-pixel ESO image – ESO Press Release

This is an 80-million-pixel picture of the star cluster RCW 38, located 5500 light-years away in the constellation Vela. RCW 38 is a young cluster containing about 2000 stars, and is bursting with star-forming activity. The picture was taken with ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA), operating in Chile’s Atacama Desert. It shows a mixture of gas, dust and stars, creating an extravagant, yet spectacular landscape. As VISTA observes infrared light, it is able to peer through most of the dust in this region, which would block our view when observing in visible light. Behind the dust, VISTA is showing young stars within dusty cocoons and cold ‘failed’ stars known as brown dwarfs, thus revealing the secrets within these young stellar nurseries.

OP 313, the blazar roars again – Media INAF

A composite image of the radio galaxy Hercules A, with the radio image obtained by Vla (New Mexico, USA) superimposed on the field photographed in optical by the orbiting Hubble Space Telescope. The optical image of the host galaxy is clearly visible in the center, and the two collimated radio jets emerging from the nuclear region. Blazars are sources of this type but fortuitously oriented with the axis of the relativistic jet in a direction close, within a few degrees, to the line of sight. Credits: NASA, ESA, S. Baum and C.

Einstein Probe detects strange cosmic explosion – Media INAF

The Einstein Probe detected the faint X-ray signal of the transient EP240315a long before its gamma-ray counterpart. This demonstrates the high sensitivity of its optics. Follow-up observations showed that the burst came from about 12.5 billion light-years away, starting its cosmic journey towards us when the universe was just 10 percent of its current age.

World’s darkest and clearest skies at risk from industrial megaproject – ESO Press Release

I cieli bui sopra l’osservatorio di Paranal, sede del Very Large Telescope (VLT) dell'ESO, offrono viste mozzafiato così chiare e così piene di stelle che potresti quasi toccarle. In cima a una piattaforma del VLT, l'ambasciatore fotografo dell'ESO Petr Horálek si protende verso un oggetto che spicca nel cielo. Si potrebbe pensare che questo corpo luminoso, come molti altri nel cielo, sia una stella, ma in realtà è un pianeta del nostro sistema solare: il gigante gassoso Giove.

Più vicino alla Terra, i quattro telescopi unitari (TU) che compongono il VLT possono essere visti sullo sfondo. Ogni TU ha uno specchio di 8,2 metri. I TU possono operare in sinergia per produrre alcune delle viste più nitide dell’Universo. Ad accompagnare i quattro TU ci sono quattro telescopi ausiliari più piccoli e mobili che hanno specchi da 1,8 metri.

Il deserto cileno di Atacama dimostra ancora una volta il suo valore come luogo ideale per il VLT dell'ESO. La lontananza dell'osservatorio significa che l'inquinamento luminoso è minimo o nullo, il che è vitale per l'astronomia e permette di ottenere viste mozzafiato - Crediti:
