A team of astronomers has performed one of the highest resolution observations in astronomical history by observing two intense regions of radiation, 20 kilometers apart, around a star 6,500 light-years away. The observation is equivalent to using a telescope on Earth to see a flea on the surface of Pluto.

NASA and private company SpaceX plan to send humans to Mars within the next 15 years — but need to figure out how to protect astronauts from the dangerous cosmic radiation of deep space. Now neuroscientists have identified a potential treatment for the brain damage caused by cosmic rays — a drug that prevents memory impairment in mice exposed to simulated space radiation.

Capitalizing on the unparalleled sharpness and spectral range of NASA’s Hubble Space Telescope, an international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.

No one has ever seen what astronomers first observed using a refurbished 75-year-old telescope in the Arizona mountains. What it was turned out to be a massive cloud of ionized hydrogen gas spewed from a nearby galaxy and then essentially ‘cooked’ by radiation from the galaxy’s central black hole.

Astronomers have used observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and ESO’s Very Large Telescope (VLT) to determine that star formation in the very distant galaxy MACS1149-JD1 started at an unexpectedly early stage, only 250 million years after the Big Bang. This discovery also represents the most distant oxygen ever detected in the universe and the most distant galaxy ever observed by ALMA or the VLT.

Astronomers have discovered an unusual laser emission that suggests the presence of a double star system hidden at the heart of the ‘spectacular’ Ant Nebula. The extremely rare phenomenon is connected to the death of a star and was discovered in observations made by European Space Agency’s Herschel space observatory.

Aspects of an otherwise Earthlike planet’s tilt and orbital dynamics can severely affect its potential habitability — even triggering abrupt ‘snowball states’ where oceans freeze and surface life is impossible, according to new research from astronomers.

Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter’s moon Europa has the ingredients to support life. The data provide independent evidence that the moon’s subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell.

A next-generation observatory, called LISA, is expected to be in space in 2034, and it will be sensitive to gravitational waves of a lower frequency than those detected by the Earth-bound Laser Interferometer Gravitational-Wave Observatory (LIGO).
