The Cherenkov Telescope Array Observatory (CTAO) is being built by astronomers to detect high-energy gamma rays from the ground. It will consist of 64 telescopes split between two locations, one in the Spanish Canary Island of La Palma and the other in the Atacama Desert of northern Chile. These telescopes use an imaging atmospheric Cherenkov telescope (IACT) design, allowing them to quickly reposition and capture transient events like gamma-ray bursts. Once completed, the CTAO will be the most sensitive instrument for studying high-energy phenomena in the universe. The Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) project, led by a team of researchers, constructed a 17-meter telescope on La Palma to observe gamma rays with energies below 100 GeV. MAGIC, along with other projects like VERITAS and HESS, has made significant discoveries in high-energy astrophysics, including detecting gamma-ray bursts and identifying sources of cosmic neutrinos. The construction of the CTAO is currently underway and will be the largest and most sensitive gamma-ray detector in the world. [Extracted from the article]

A recent discovery by researchers at Radboud University in the Netherlands has shed light on the mysterious nature of gamma ray bursts (GRBs), the most powerful explosions in the universe. The researchers found that a particular GRB, known as GRB221009A, contained an energetic peak at about 10 megaelectronvolts, which suggests the involvement of matter and antimatter annihilating. This finding challenges current models of GRBs and provides insight into the composition of these cosmic explosions. The discovery of this distinctive line in the spectrum of a GRB is considered a significant surprise in the field of astrophysics. [Extracted from the article]

This article explores the hidden universe beyond what our eyes can see, emphasizing that visible light is just a small portion of the electromagnetic spectrum. It discusses how astronomers use telescopes and detectors to observe and study different wavelengths of light, such as infrared, X-rays, and radio waves, emitted by cosmic objects in space. The article provides examples of the detection of gamma rays from exploding stars and the discovery of cosmic microwave background radiation from the Big Bang. It also highlights the use of telescopes to create composite images of celestial objects, using the example of Cassiopeia A, and the effectiveness of infrared light in locating asteroids.

The article discusses the discovery of radiotrophic fungi, which can use radiation as an energy source for growth. Topics include the resistance of certain fungal species to radiation, the role of melanin in their growth, potential applications of fungal melanin in various fields, and the need for collaboration with plant biologists to further understand this phenomenon."

According to an article in New Scientist, researchers at the Max Planck Institute for Nuclear Physics in Germany have discovered that microquasars, small black holes that emit jets of material from orbiting stars, may be the source of the most powerful cosmic rays observed on Earth. Unlike larger quasars, microquasars contain a black hole with a star-like mass. The researchers observed gamma radiation from the jets of microquasars and believe that it is produced by electrons colliding with a barrier and being accelerated. If this process also occurs for heavier particles, a microquasar closer to Earth could potentially explain the high-energy cosmic rays that occasionally reach our atmosphere.
