Astronomers observe eclipses of pulsar PSR J0024−7204O
Using the MeerKAT radio telescope, astronomers have observed eclipses in the radio emission of a pulsar known as PSR J0024−7204O. Results of the observational campaign, published on the preprint server arXiv, could help ...
Astronomers explain rapid formation of organic macromolecules in protoplanetary disks around young stars
An international team of researchers led by the University of Bern has used observation-based computer modeling to find an explanation for how macromolecules can form in a short time in disks of gas and dust around young ...

Ever see a star explode? You're about to get a chance very soon
Every clear night for the last three weeks, Bob Stephens has pointed his home telescope at the same two stars in hopes of witnessing one of the most violent events in the universe—a nova explosion a hundred thousand times ...

New study simulates gravitational waves from failing warp drive
Imagine a spaceship driven not by engines, but by compressing the spacetime in front of it. That's the realm of science fiction, right? Well, not entirely. Physicists have been exploring the theoretical possibility of "warp ...

Globular cluster NGC 6558 explored with Gemini Observatory and Hubble Space Telescope
Using the Gemini Observatory and the Hubble Space Telescope (HST), an international team of astronomers has investigated a Galactic globular cluster known as NGC 6558. Results of the new study, published July 22 on the pre-print ...
Dark matter seen through forest: Study examines matter distribution and supports unknown influence or new particle
The dense peaks in the wavelength distribution graph observed in a Lyman-Alpha forest indeed resemble many small trees. Each of those peaks represents a sudden drop in "light" at a specific and narrow wavelength, effectively ...

Not one, but two meteor showers are about to peak—here's how to catch the stellar show
On any clear night, if you gaze skywards long enough, chances are you'll see a meteor streaking through the sky. Some nights, however, are better than others.

Study sheds more light on the nature of pulsar PSR J1227−6208
Astronomers from the Max Planck Institute for Radio Astronomy (MPIfRA) in Bonn, Germany and elsewhere have inspected a recycled pulsar known as PSR J1227−6208. The new study, published July 18 on the preprint server arXiv, ...
Fermi Telescope finds new feature in brightest gamma-ray burst yet seen
In October 2022, astronomers were stunned by what was quickly dubbed the BOAT—the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA's Fermi Gamma-ray Space Telescope ...

How NASA's Roman Space Telescope will illuminate cosmic dawn
Today, enormous stretches of space are crystal clear, but that wasn't always the case. During its infancy, the universe was filled with a "fog" that made it opaque, cloaking the first stars and galaxies. NASA's upcoming Nancy ...

Creation of a deep learning algorithm to detect unexpected gravitational wave events
Starting with the direct detection of gravitational waves in 2015, scientists have relied on a bit of a kludge: they can only detect those waves that match theoretical predictions, which is rather the opposite way that science ...
Next-generation Event Horizon Telescope to unlock mysteries of black holes
The prospect of actually resolving the event horizon of black holes feels like the stuff of science fiction, yet it is a reality. Already, the Event Horizon Telescope (EHT) has resolved the horizon of the black holes at the ...

Dark matter flies ahead of normal matter in mega galaxy cluster collision
Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter. The two clusters each contain thousands ...
