New planetary mass object discovered in quadrupole system
This week’s photo shows the unique star system HIP 81208, taken by ESO’s Very Large Telescope (VLT) in Chile. Astronomers believe that HIP 81208 is…
Matter accounts for 31% of the total amount of matter and energy in the universe.
Like Goldilocks, the team compared the number of galaxy clusters measured with predictions from numerical simulations to determine which answer was “just right.” Image credit:…
Supermassive exoplanets are denser than steel, scientists say
The newly discovered exoplanet exhibits so unusual properties that astronomers believe it must have undergone a giant impact some time ago. Although TOI-1853b is an…
Matter Ejection Explains Strange High-low Mode Changes in Distant Millisecond Pulsars
The millisecond pulsar PSR J1023+0038 is known to switch between two luminance modes almost constantly, but this has been a mystery until now. PSR J1023+0038…
First observation of the orbit of the accretion disk of a supermassive black hole
Astronomers have discovered hints of an accretion disk in the active galactic nucleus of galaxy III Zw 002 for the first time using the Gemini…
A new study suggests that dark matter interacts with gravity non-locally
A new SISSA study suggests that dark matter interacts with gravity in non-local ways, challenging traditional theories and offering new insights into the nature of…
Researchers study hard X-ray emission from low-mass X-ray binaries of neutron stars
Correlation between the photon index (Γ) of a rigid X-ray tail and its flux (in ∼30–200 keV, in units of 109 ergs cm−2 s−1). The…
Cold stars with powerful winds complicate habitability
Scientists at the Leibniz Institute for Astrophysics in Potsdam (AIP) have conducted the first systematic characterization of the properties of stellar winds in a sample…
Astronomers find evidence of a new method of formation of giant planets
At the center of this image is the young star V960 Mon located more than 5,000 light-years away in the constellation Monoceros. Dusty material with…
