Does the Milky Way have too many satellite galaxies?
The Large and Small Magellanic Clouds are well-known satellite galaxies of the Milky Way, but there are more. It is surrounded by at least 61 within 1.4 million light years (for context the Andromeda galaxy is 2.5 million light years away) but there.....»»

NOAA releases imagery from world"s first operational space-based coronagraph
NOAA today shared the first images from the Compact Coronagraph (CCOR-1), a powerful solar telescope onboard the new GOES-19 satellite. CCOR-1, the world's first operational, space-based coronagraph, began observing the sun's corona, the faint outerm.....»»

A new view of the in-between years of our universe
Just like we use photos to reflect on memories of our past, astrophysicists want to use images of far-off galaxies to understand what the universe was like in its juvenile years. But current imaging technology can only reach so far back in history—.....»»
Observations explore the nature of stellar stream Icarus
Astronomers from Italy and Chile have investigated an accreted stellar stream named Icarus in the Milky Way's disk. Results of the study, detailed in a research paper published October 16 on the preprint server arXiv, yield crucial information regard.....»»
Combining satellite methods provides drought detection from space
Observing sites like the Amazon basin from space has underscored the capability of satellites to better detect signs of drought, according to a new study......»»
Satellite-derived data on artificial light at night indicate rapidly increasing industrial activities in the Arctic
More than 800,000 km2 of the Arctic were affected by human activity in 2013, according to an analysis of satellite-derived data on artificial light at night. On average, 85% of the light-polluted areas are due to industrial activities rather than urb.....»»
To the astonishment of forecasters, a tiny hurricane just sprang up near Cuba
As of Saturday evening, hurricane-force winds extended just 5 miles from the center. A hurricane so small that it could not be observed by satellite formed this weekend, surprisin.....»»
A near-Earth microquasar emerges as a source of powerful radiation
Modern astronomy has clung to the belief that the relativistic outflows or jets, responsible for the existence of electromagnetic radiation of particularly high energies, are located in the nuclei of active galaxies distant from Earth. However, a dif.....»»
Rare ultra-luminous nova spotted in the Small Magellanic Cloud
A rare, extremely luminous X-ray outburst has been observed in the Small Magellanic Cloud, a dwarf galaxy that is a close neighbor of our own Milky Way galaxy. The observations, made by the Neil Gehrels Swift Observatory and other telescopes, were de.....»»

Roadside Assistance via satellite now available in the UK, with Green Flag
Apple last year launched its Roadside Assistance via satellite feature in the US, intended to provide help to those stranded by car trouble in areas without mobile coverage. That service has now been quietly extended to the UK. You’ll need an iP.....»»

Trace gas measurements could advance carbon cycle predictions
A novel method for estimating the rate of photosynthesis from land plants reveals that satellite observations—the current gold standard for quantifying terrestrial carbon uptake—underestimate this important metric, a result that could inform and.....»»

EarthCARE synergy reveals power of clouds and aerosols
With the initial images from each of the instruments aboard ESA's EarthCARE satellite now in hand, it's time to reveal how these four advanced sensors work in synergy to measure exactly how clouds and aerosols influence the heating and cooling of our.....»»

Astronomers find Webb data conflict with reionization models
Reionization is a critical period when the first stars and galaxies changed the physical structure of their surroundings, and eventually the entire universe. Established theories state that this epoch ended around 1 billion years after the Big Bang......»»
A sharper view of the Milky Way with Gaia and machine learning
A group of scientists led by the Leibniz Institute for Astrophysics Potsdam (AIP) and the Institute of Cosmos Sciences at the University of Barcelona (ICCUB) have used a novel machine learning model to process data for 217 million stars observed by t.....»»
