These observations have led to the highest spectral resolution multi-dimensional datasets for over a million stars in the Milky Way. Previous GALAH data releases have led to many significant discoveries about the evolution of the Milky Way, the existence of exoplanets, hidden star clusters, and ...
C., Yazici, S., Smajic, S., Wiest, M., Araujo-Hauck, C., Wank, I.: Beating the confusion limit: the necessity of high angular resolution for probing the physics of Sagittarius A* and its environment: opportunities for LINC-NIRVANA (LBT), GRAVITY (VLTI) and and METIS (E-ELT). In...
The wider the distance between the two farthest telescopes in the network, the greater the resolution, and the more telescopes there are in the network, the greater the sensitivity. The EHT managed to image the black hole in the center of our Milky Way galaxy, Sagittarius A*, as well as ...
From this, they found that the total halo mass of the Milky Way was about 1.04 x 1012 (over 1 trillion) solar masses, with a 20 percent margin of error. This estimate places much tighter constraints on the Milky Way's mass than previous estimates, and could have some significant implicati...
Celestial magnetic fields are notoriously difficult to observe. SOFIA'snewest instrument, the High-resolution Airborne Wideband Camera-Plus, or HAWC+, uses far-infrared light to observe celestial dust grains, which align perpendicular to magnetic field lines. From these results, astronomers can infer ...
The high-resolution spectrometer to measure the radial velocity of the stars by acquiring high-resolution spectra in the spectral band 847-874 nm (field lines of calcium ion) for objects up to magnitude 17 , The telemetric link with the satellite is about 1 Mbit/s on average, while the tot...

‘interestingness’ across the Milky Way. Users drawing on the low zoom levels draw broader, less-accurate boxes because they are constrained by low image resolution, users on the highest zoom level draw very precise images and may draw multiple regions within the same larger box. The effect ...
