A near-complete census of our interstellar neighborhood hopes to answer how stars, brown dwarfs and rogue planets form ...

Researchers said the remaining 21 other major sites – three-quarters of all the major observatories – are all above this level. For ground-based telescopes, the lowest pointing direction is ...

but the researchers also measured the average brightness at altitudes of 30 degrees — the lowest that a telescope at a ground-based observatory can point — as well as for the first 10 degrees ...

Scientists have achieved a groundbreaking feat by detecting a 13-billion-year-old microwave signal from the Cosmic Dawn using ...

The research represents the first time ground-based observations have captured signals from the Cosmic Dawn, according to ...

This clutter is obviously a big problem for ground-based observatories, which sit below everything in orbit. But several observatories, including the Hubble Space Telescope, sit in low-Earth orbit ...

The location of the logos shows the projected start of science operations for a range of missions and observatories – from space- and ground-based observatories across the spectrum, to multimessenger ...

The light from planets, stars, and galaxies is faint compared to the nearby Sun, so ground-based observatories do have to wait until nighttime to see them. But there are other ways to study the ...

Related Stories Ground-based observatories, like the High Energy Stereoscopic System (H.E.S.S.) in Namibia, overcome this limitation by observing the particle showers triggered when cosmic rays ...

Astronomers can also use ground-based observatories, like the Madrid Deep Space Communications Complex (the third member of NASA's Deep Space Network), to capture images of asteroids as they pass ...
