Indian and Taiwanese astronomers recently upgraded Giant Metrewave Radio Telescope (uGMRT) to snoop around the galaxy cluster Abell 2108. And guess what? They stumbled upon a second, way bigger radio relic that’s like, totally different from the first one they knew about in the same cluster.

In 2019, the Event Horizon Telescope (EHT) unveiled the first-ever images of M87. It was a mind-blowing moment for astronomy. M87 is a supermassive black hole at the center of the galaxy Messier 87. The EHT dropped the first snapshots of M87. It was like getting an up-close look at a supermassive black hole for the first time ever!

Tiny meteorites from the icy outer reaches of the Solar System might be the reason nitrogen ended up near Earth. Yes, we are talking about the early days of our solar system. A team of scientists from the University of Hawai’i at Manoa along with Kyoto University and others from around the globe recently published their discovery in Nature Astronomy.

Jonathan Dodd and Professor René Oudmaijer’s recent research at the University of Leeds challenges the assumption that massive Be stars are mainly found in double star systems. The study, however, suggests evidence supporting the idea that these stars might be part of triple star systems. Thus, introducing a new perspective in stellar science.

Our planet, Earth, is not merely a rock in space but an interesting entity with various forces acting within and outside of it. For instance, magnetosphere. Earth’s core consists of molten iron. This liquid iron creates electric currents. Which, consequently, generate a magnetic field that surrounds Earth. This magnetic field extends far out into space, creating the magnetosphere. It acts as a formidable defence against the solar wind.

In an international collaboration between astronomers from University of Padua (Italy), the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), there are indications that multiple black holes might exist within the Hyades cluster.

Rovers on Mars are constantly monitored and maneuvered by humans on Earth. However, robots on missions to Saturn or Jupiter’s moons can’t get timely commands from Earth. What if these machines could make decisions on the fly? Instead of waiting for an “order”, how about these bots making autonomous choice? Thinking on these lines of thought, researchers at the University of Illinois Urbana-Champaign came up with a cool way for these robots to decide where and how to collect terrain samples on their own.

The surface area of Europa, one of Jupiter’s moons, is slightly smaller than Earth’s Moon. Yet it has garnered a lot of attention from scientists as a potential site for extra-terrestrial life. Here are some of the reasons, why it is considered as potential for hosting life: Surface and Ice Shell: The surface of Jovian moon is covered by a layer of ice that is believed to be several kilometers thick. When it comes to the entire solar system, its icy crust is one of the smoothest. This implies that…

Dr. Ore Gottlieb is a theoretical high energy astrophysicist. Currently, he is occupying Rothschild/CIERA Postdoctoral Fellowship position in Astrophysics at Northwestern University. His recent work on “Dying stars’ cocoons could be new source of gravitational waves” caught our attention and so we tried to touch base with him for an interview. We got lucky, as he agreed to spend some time with us.

Gravitational waves are ripples in the fabric of spacetime caused by the acceleration of massive objects. The main source of detecting gravitational waves are the mergers of binary systems consisting of black holes and neutron stars. Till now, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo detector have successfully identified gravitational waves.

Researchers at Japan have discovered some new information about why all amino acids found on Earth are in a specific shape called “left-handed” or “L-form.” The team studied amino acids found in a meteorite called the Murchison meteorite. They also used computer simulations based on physics to understand how this shape came about.

Radiation belts are zones of charged particles, primarily electrons and protons, trapped by a planet’s magnetic field. They are typically found around planets with a significant magnetic field, such as Earth or Jupiter. These belts produce various radiations, including radio emissions, which can be detected and studied by radio telescopes.

When a star runs out of fuel, it eventually reaches the end of its life cycle and begin to expand. It swells to hundred or even a thousand times its original size. The process is called as a “red giant” phase. The progression enables the star’s outer layers to become less dense. Consequently, the star starts to swell outwards. In some cases, the star may expand so much that it engulfs any nearby planets.

Short-term exposure to altered gravity, such as the brief periods of weightlessness experienced during parabolic flights, is generally not considered to be harmful to human health. However, it’s important to note that even short periods of altered gravity can slightly thought not exponentially affect the body in various ways. For example, during periods of weightlessness, fluids tend to shift from the lower body to the upper body, which can cause a decrease in blood volume and an increase in pressure in the head and upper body. This can result in…
