Giant ‘chimneys’ vent X-rays from Milky Way’s core

By surveying the centre of our Galaxy, ESA’s XMM-Newton has discovered two colossal ‘chimneys’ funneling material from the vicinity of the Milky Way’s supermassive black hole into two huge cosmic bubbles.

Copernicus Sentinel-1 maps floods in wake of Idai

As millions of people in Mozambique, Malawi and Zimbabwe struggle to cope with the aftermath of what could be the southern hemisphere’s worst storm, Copernicus Sentinel-1 is one of the satellite missions being used to map flooded areas to help relief efforts.

Taking gravity from strength to strength

Ten years ago, ESA launched one of its most innovative satellites. GOCE spent four years measuring a fundamental force of nature: gravity. This extraordinary mission not only yielded new insights into our gravity field, but led to some amazing discoveries about our planet, from deep below the surface to high up in the atmosphere and beyond. And, this remarkable mission continues to realise new science today.

ESA’s Hera asteroid mission borrows eyes of NASA’s Dawn

The mission to the smallest asteroid ever explored will employ the same main camera as the mission to the largest asteroids of all. ESA’s proposed Hera spacecraft to the Didymos asteroid pair has inherited its main imager from NASA’s Dawn mission to the Vesta and Ceres asteroids.

La nana a la vista

En Carlos Uriarte ho ha aconseguit. Ha pogut fotografiar la companya de Sirius. Sirius B, com se l'anomena, és una enana blanca débil que està enlluernada per l'estrella més brillant del cel. Tot això en dificulta l'observació. Ens ho explica ell mateix.

"Aprofitant que la B de Sirius es troba en un dels punts més llunyans de la seva germana vaig posar a capturar amb el Takahashi Mewlon 210 i la ASI183MMC. Amb el pixel tant petit que te puc fer ROI's molt petits i poder veure detalls.

Sirius B es veia be, malgrat el seeing i la pròpia turbulència. En un video de poc més d'un minut vaig acumular suficients fotogrames per poder apilar i extreure algo de detall."
