Good morning, this is Abel. Today's highlight is the story of NASA's twin Mars probes, ESCAPADE, which will fire their ...

Galactic archaeologists are using precise measures and larger sample sizes afforded by new missions to tease apart minute differences between groups of stars, revealing the history of the Milky Way ...

Gas-rich dwarf galaxies appear to retain only about a tenth of the oxygen their stars have made, according to a census of 37 nearby systems using data from the NASA/ESA Hubble Space Telescope.

Astronomers working mostly in Chile dated VVV CL001, a faint globular cluster buried behind dust near the galactic center, at ...

Supernova-driven winds strip dwarf galaxies of far more oxygen than models predict, offering new clues about how galaxies evolve over cosmic time.

Astronomers using early data from Rubin Observatory have identified two previously hidden companions of the Milky Way. One is ...

Nova dust formation in nova V488 Sge was detected in real time by the MIRAGE infrared camera at Kitt Peak, which recorded a 0 ...

"The Sagittarius stream gives us an opportunity to recover part of the original galaxy's structure and compare it with present-day dwarf galaxies," said Prof. ZHAO Gang of NAOC, a co-corresponding ...

We outline the results of a study of the chemical composition of 14 stars in the Sagittarius dwarf spheroidal galaxy (Sgr dSph). For the Sgr dSph stars with [Fe/H >= - 1 the abundances are highly ...

No other constellation has so much to offer – and shows us so little of it. Behind the constellation Sagittarius lies the center of our Milky Way, fifteen Messier objects crowd together here in the ...
