Observers detect intraday variability of blazar 1ES 1426+42.8
Astronomers report the detection of optical intraday variability of a blazar known as 1ES 1426+42.8. The new findings, presented in a paper published in the September issue of Monthly Notices of the Royal Astronomical Society, ...
Citizen science collaboration yields precise data on exoplanet WASP-77 A b
A planet swings in front of its star, dimming the starlight we see. Events like these, called transits, provide us with bounties of information about exoplanets—planets around stars other than the sun. But predicting when ...

Exoplanets could be hiding their atmospheres
Most of the exoplanets we've discovered orbit red dwarf stars. This isn't because red dwarfs are somehow special, simply that they are common. About 75% of the stars in the Milky Way are red dwarfs, so you would expect red ...

Plants could still grow well under alien skies
Photosynthesis changed Earth in powerful ways. When photosynthetic organisms appeared, it led to the Great Oxygenation Event. That allowed multicellular life to evolve and resulted in the ozone layer. Life could venture onto ...

Could interstellar quantum communications involve Earth or solve the Fermi paradox?
Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit scouring light from the ...
Astronomers can't agree on how fast the universe is expanding. New approaches aim to break the impasse
It is almost 100 years since scientists discovered the universe is expanding. In the decades that followed, the accuracy of the measurements, and interpretations and implications of this discovery, were a source of fierce ...

Observations provide crucial insights into the nature of a white dwarf–brown dwarf binary
Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September ...
Artemis I mission data show astronauts sent to the moon aboard Orion will be protected from radiation
According to a large team of technical and health specialists, astronauts aboard the Orion spacecraft will be well protected from radiation when the Artemis II mission travels to the moon and back next year.
New study uncovers unexpected interaction between Mars and the solar wind
Scientists of the Swedish Institute of Space Physics (IRF) in Kiruna and Umeå University find that under certain conditions the induced magnetosphere of Mars can degenerate. The findings are presented in a new study published ...
