Gravity surveys using a mobile atom interferometer

Mobile gravimetry is an important technique in metrology, navigation, geodesy and geophysics. Although atomic gravimeters are presently used for accuracy, they are constrained by instrumental fragility and complexity. In ...

Astronomers discover three new faint dwarf galaxies

By analyzing the data from the Dark Energy Survey (DES), an international team of astronomers has conducted a search for nearby faint dwarf galaxies. In result, they detected three such objects around the Sculptor Galaxy. ...

The Arctic's greening, but it won't save us

There was a hope that as more plants start to grow in Arctic and boreal latitudes as our warming climate makes those regions more hospitable for plants, those photosynthesizing plants would work to help sequester the atmospheric ...

Dark Energy Survey physicists open new window into dark energy

The universe is expanding at an ever-increasing rate, and while no one is sure why, researchers with the Dark Energy Survey (DES) at least had a strategy for figuring it out: They would combine measurements of the distribution ...

Hubble spots double quasars in merging galaxies

NASA's Hubble Space Telescope is "seeing double." Peering back 10 billion years into the universe's past, Hubble astronomers found a pair of quasars that are so close to each other they look like a single object in ground-based ...

Scientists determine the origin of extra-solar object 'Oumuamua

In 2017, the first interstellar object from beyond our solar system was discovered via the Pan-STARRS astronomical observatory in Hawaii. It was named 'Oumuamua, meaning "scout" or "messenger" in Hawaiian. The object was ...

Large supernova remnant detected by eROSITA

Using the extended Röntgen Survey Imaging Telescope Array (eROSITA) instrument onboard the Spektr-RG spacecraft, astronomers have detected in X-rays a new large supernova remnant (SNR). The newfound object, dubbed "Hoinga," ...
