The discovery of the dwarf galaxy Andromeda XXXV --located roughly 3 million light-years away and the smallest yet found in the Andromeda system -- is forcing astronomers to rethink how galaxies ...
Scientists are designing a satellite and instruments capable of detecting space debris as small as 1 centimeter, less than one-half inch. Debris that small, which cannot currently be detected from the ground, can damage satellites and other ...
Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. What backyard observers don't see is a swarm of nearly three dozen small ...
An international team of scientists has called for the creation of an 18th addition to the United Nations Sustainable Development Goals, which would aim to mitigate against the accumulation of space junk in Earth's orbit. They believe a new SDG18 ...

The ability to have access to the Internet or use a mobile phone anywhere in the world is taken more and more for granted, but the brightness of Internet and telecommunications satellites that enable ...

Scientists have trained a machine learning model in outer space, on board a satellite. This achievement could revolutionize the capabilities of remote-sensing satellites by enabling real-time ...

Researchers have tested the software of three satellites. And they found many standard security mechanisms ...

Extreme space weather threatens vital satellites orbiting the Earth, including the Global Navigation Satellite Systems (GNSS) which pass through the heart of the outer radiation belt. New research ...

On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings ...

Space weather can interfere with spaceflight and the operation of satellites, but the phenomenon is very difficult to study on Earth because of the difference in gravity. Researchers effectively ...

ESA's novel Aeolus satellite reliably measures wind speed also in higher air layers and thus in a region of the atmosphere where other direct global wind measurements are relatively sparse. This ...

Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report describes the final results from the MICROSCOPE ...

Researchers report an experimental demonstration of a space-to-ground quantum key distribution (QKD) network using a compact QKD terminal aboard the Chinese Space Lab Tiangong-2 and four ground ...

Students have completed a comprehensive brightness study to characterize mega-constellation satellites cluttering the ...

Changes in atmospheric density after sunset can cause hot pockets of gas called 'plasma bubbles' to form over the Earth's equator, resulting in communication disruptions between ...

The European Gaia space mission has produced an unprecedented amount of new, improved, and detailed data for almost two billion objects in the Milky Way galaxy and the surrounding cosmos. The Gaia ...
