Charged cosmic rays, high-energy clusters of particles moving through space, were first described in 1912 by physicist Victor Hess. Since their discovery, they have been the topic of numerous astrophysics studies aimed at ...
An international team of astronomers has employed a set of space telescopes to observe a peculiar nuclear transient known as AT 2019avd. Results of the observational campaign, presented in a paper published December 21 on ...
Biomanufacturing based in space can improve the sustainability of deep space exploration. Bioprocessing systems to advance biomanufacturing for space applications need to be developed. In a new report now published in npj ...
Magnetotactic bacteria can form magnetofossils like magnetic nanocrystals as observed in the Martian meteorite ALH84001, which held a special place in the field of astrobiology primarily in the early 90s. While the flourishing ...
Using the Neutron star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), European astronomers have performed spectral analysis of a low-mass X-ray binary known as XTE J1810–189. Results ...
Using the Nuclear Spectroscopic Telescope Array (NuSTAR) spacecraft and the Neutron star Interior Composition Explorer (NICER) instrument onboard the International Space Station, astronomers have inspected an ultracompact ...
After July 2023 was confirmed as the warmest month on record for planet Earth, a new study has shown the world's tropical forest canopies may be closer to critical high-temperature thresholds than previously known.

A team of computational social scientists at George Mason University has found via simulations that 22 people is the minimum number needed to start a human colony on Mars. The group has posted a paper describing their simulation ...
Although technically challenging, space experiments are a scientifically important aspect of astrobiology and astrochemistry investigations. The international space station (ISS) offers an excellent example of a long-term ...
Using the AstroSat spacecraft and the Neutron star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), Indian astronomers have observed an X-ray binary known as GX 349+2. Results of the observational ...
A space station is an artificial structure designed for humans to live in outer space. To date, only low earth orbital (LEO) stations have been implemented, otherwise known as orbital stations. A space station is distinguished from other manned spacecraft by its lack of major propulsion or landing facilities—instead, other vehicles are used as transport to and from the station. Space stations are designed for medium-term living in orbit, for periods of weeks, months, or even years. The only space station currently in use is the International Space Station. Previous stations include the Almaz & Salyut series, Skylab and Mir.
Space stations are used to study the effects of long-term space flight on the human body as well as to provide platforms for greater number and length of scientific studies than available on other space vehicles. Since the ill-fated flight of Soyuz 11 to Salyut 1, all manned spaceflight duration records have been set aboard space stations. The duration record for a single spaceflight is 437.7 days, set by Valeriy Polyakov aboard Mir from 1994 to 1995. As of 2009[update], three astronauts have completed single missions of over a year, all aboard Mir.
