New test of dark energy and expansion from cosmic structures
A new paper has shown how large structures in the distribution of galaxies in the Universe provide the most precise tests of dark energy and cosmic expansion yet.

Read moreUltra-bright X-ray source awakens near a galaxy not so far away
A new ultra-bright source of X-rays has awakened in between our galactic neighbours the Magellanic Clouds, after a 26-year slumber. This is the second-closest such object known to date, with a brightness greater than a million Suns.

Read moreDiscovery of long sought tiny explosions on the Sun
The mechanism responsible for heating the corona to two million degrees, especially for the quiet Sun, has remained an enduring mystery. Scientists have now found the first direct observational evidence in support of one of the proposed mechanisms for heating the quiet corona. They have discovered tiny flashes of radio light from all over the Sun, smoking guns for tiny magnetic explosions which convert the copious magnetic energy present in the quiet corona into heat.

Read moreLarge simulation finds new origin of supermassive black holes
In this theory, the precursors of supermassive black holes grow by swallowing up not only interstellar gas, but also smaller stars as well. This helps to explain the large number of supermassive black holes observed today.

Scientists have combined theory with both observations and laboratory studies and determined that a class of stellar explosions, called classical novae, are responsible for most of the lithium in our galaxy and solar system.

An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links might suggest that the early universe could have been spinning.

Read moreScientists have discovered a new type of matter inside neutron stars
A research group has found strong evidence for the presence of exotic quark matter inside the cores of the largest neutron stars in existence. The conclusion was reached by combining recent results from theoretical particle and nuclear physics to measurements of gravitational waves from neutron star collisions.

Read moreAstronomers find cosmic golden needle buried for two decades
Astronomers made innovative use of their time while sheltering at home due to the pandemic by combing through W. M. Keck Observatory and NASA archive data. They rediscovered the first Einstein ring and found the distance of its source was never measured. The researchers are the first to make the calculation and found the quasar to be 10 billion light-years away, or a redshift of z=1.849.

Read more4-billion-year-old nitrogen-containing organic molecules discovered in Martian meteorites
Using advanced techniques, scientists have detected organic compounds containing nitrogen in Martian meteorites which were ejected from Mars' surface some 15 million years ago, proving that evidence for early life can be preserved and detected today.

Astronomers are finding that planets have a tough time forming in the rough-and-tumble central region of the massive, crowded star cluster Westerlund 2. Located 20,000 light-years away, Westerlund 2 is a unique laboratory to study stellar evolutionary processes because it's relatively nearby, quite young, and contains a large stellar population.

Active galactic nuclei (AGNs) play a major role in galaxy evolution. Astronomers have now used a record-sized sample of galaxies to confirm that galaxy mergers have a positive effect on igniting AGNs.
