Dark energy remains among the greatest puzzles in our understanding of the cosmos. In the standard model of cosmology called the Lambda-CDM, it is accounted for by adding a cosmological constant term in Einstein's field equation first introduced by Einstein himself. This constant is very small and positive and lacks a complete theoretical understanding of why it has such a tiny value. Moreover, dark energy has some peculiar features, such as negative pressure and does not dilute with cosmic expansion, which makes at least some of us uncomfortable.

A higher-dimensional model can help explain cosmic acceleration without dark energy

Neutrinos are the "ghost particles" in the Standard Model of Particle Physics. This is because they interact weakly with ordinary matter. An interesting property of neutrinos is that they can change their identities or "flavors" when they interact. Researchers recently found that the neutrinos in a very dense environment can...

What is a galaxy redshift survey? A galaxy redshift survey maps the universe by measuring how much light from galaxies stretches as they move away. This stretching, called redshift, helps scientists understand the universe's expansion. Imagine looking at a star and noticing its light turning redder. That shift tells us it's moving away. By surveying many galaxies, astronomers can create a 3D map of the cosmos. These maps reveal the structure of the universe, showing clusters, voids, and superclusters. They also provide clues about dark energy and dark matter. Galaxy redshift surveys are like cosmic roadmaps, guiding our understanding of space.

Researchers have developed a method to predict the speed and arrival time of coronal mass ejections (CMEs) before they fully erupt from the Sun. This advancement utilizes the measurement of the critical height in Active Regions on the Sun to enhance the accuracy of space weather forecasts. These predictions are crucial for protecting Earth’s technological infrastructure from geomagnetic storms that can disrupt satellites, power grids, and communication networks.

A study has revealed that galaxies possess a regulatory mechanism similar to a heart and lungs, which controls their growth by limiting gas absorption. This mechanism, involving a supermassive black hole and its jet emissions, prevents galaxies from expanding too rapidly, ensuring their longevity and preventing premature aging into “zombie” galaxies.

Astronomers are intrigued by the gas giant exoplanetWASP-69b due to the unusually long trail of gas it is leaving behind, approximately seven times longer than its radius. Situated close to its star, the planet's atmosphere is stripped away by the intense radiation from the stellar wind, creating this distinctive tail. Led by researchers from UCLA, observations from the WM Keck Observatory in Hawaii and high-resolution spectrograph readings confirmed the presence of this extended tail and revealed the loss of hydrogen and helium in significant amounts.

This year’s area of low oxygen in the Gulf of Mexico is larger than average, the National Oceanic and Atmospheric Administration (NOAA) announced on Thursday. The “dead zone” is approximately 6,705 square miles , as measured last week. Within NOAA’s 38 years of measuring the dead zone, this year’s assessment marks the 12th-largest area of low to no oxygen, which can kill fish and marine life.
