Scientists are using advanced simulations to explore the aftermath of neutron star collisions, where remnants might form and avoid collapsing into black holes.

This research not only sheds light on the dynamics and cooling of these remnants through neutrino emissions but also provides crucial insights into the behavior of nuclear matter under extreme conditions. The findings contribute to our understanding of astronomical events and the conditions that may or may not lead to black hole formation.

Mysterious aftermath of neutron star collisions.

The James Webb Space Telescope (JWST) is the largest and most powerful space telescope built to date. Since it was launched in December 2021 it has provided groundbreaking insights. These include discovering the earliest and most distant known galaxies, which existed just 300 million years after the Big Bang.

Utilizing the James Webb Space Telescope, astronomers have refined the measurement of the Hubble constant by studying SN H0pe, a gravitationally lensed Type Ia supernova.

This approach, integrating gravitational lensing and time-delay observations, offers a more precise determination of the universe’s expansion rate, helping reconcile some differences between past measurements.

Measuring the Hubble constant, which defines the rate at which the universe is expanding, is a dynamic field of study for astronomers globally. These researchers analyze data from both terrestrial and orbital observatories. NASAs James Webb Space Telescope has already made significant contributions to this discussion. Earlier this year, astronomers employed Webb data that included Cepheid variables and Type Ia supernovae—both reliable cosmic distance markers—to validate previous measurements of the universe’s expansion rate made by NASA’s Hubble Space Telescope.

Watching for changes in the Mars ’ orbit over time could be a new way to detect passing dark matter.

Dark matter, potentially in the form of primordial black holes, could be revealing its presence through subtle influences on Mars’ orbit. These black holes, theorized remnants from the early universe, might be detectable every decade as they pass through the solar system, offering a new way to study the elusive dark matter.

Physicists are obsessed with black holes, but we still don’t know what’s going on inside of them. One idea is that black holes do not truly exist, but instead they are big quantum objects that have been called fuzzballs or frozen stars. This idea has a big problem. Let’s take a look.

One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes more than 85% of the matter in the universe), but we have never seen it directly and still do not know what it is.

Following the accelerated expansion discovery of the Universe, scientists introduced dark energy concepts, which faced issues like the cosmological constant problem.

Researchers at IKBFU developed a holographic dark energy model based on quantum gravity, which views the Universe as a hologram. This model, initially unstable, was refined to treat dark energy as perturbations, stabilizing it. It is now being tested against observational data for accuracy.

The right value for the expansion rate of the universe continues to elude astronomers.

Researchers at CERN have observed an exceptionally rare particle decay event, potentially paving the way to uncover new physics beyond the current understanding of fundamental particles and their interactions.

This decay is extraordinarily uncommon—according to the Standard Model ℠ of particle physics, which describes particle interactions, fewer than one in every 10 billion kaons undergo this specific decay.
