Black Hole Mergers: Dark Matter Might Be the Missing Link

Launched in 1977, Voyager 1 is one of the farthest probes that we’ve sent so far. As of July 2024, it’s a whopping 24.4 billion kilometers away from Earth, making it the most distant human-made object ever. Yet, there are things in the space that we have absolutely zero clue. Yes, I’m referring to – Dark Matter. Dark matter helps slow the black holes down and lets them come together for supermassive black hole mergers, at least the recent research says so. Typically elusive, this invisible matter seems to play…

Gravitational Wave Memory: A Tool for Measuring Spacetime Symmetries

When we talk about the fabric of reality, in terms of physics, we deal with interesting abstractions and tonnes of complexities. One such intriguing concept of Einstein’s theory of general relativity is the existence of gravitational waves. As the name suggests, these ripples are generated in the spacetime by some of the universe’s most violent and energetic processes, such as mergers of cosmic stars or dent in the landscape due to black holes. Interestingly, whenever these waves pass through, they leave a measurable imprint on the relative positions of objects—a…

Planetary Puzzle: Aquodiium Ions may Influence Uranus and Neptune’s Magnetic Fields

Scientists from Skoltech and their Chinese colleagues have discovered conditions that might allow for the existence of a unique ion called aquodiium. This ion is essentially a water molecule that has gained two extra protons. This means, the “regular” H₂O formula with two additional protons (H⁺), will make its chemical formula H₅O²⁺.

Analyzing Pulsars: To Detect Subnanohertz Gravitational Waves

Detecting gravitational waves have always been a challenging task. It is caused due to high energetic events, like colliding black holes or neutron stars. And so, the phenomenon is like ripples on the fabric of space-time. By the time, this effect reaches us (from deep space), the signals become extremely weak. And hence, too faint to detect.

Cosmic Conundrum in the Milky Way: Lightest Black Hole or Heaviest Neutron Star

Exciting news from the cosmos! Astronomers from around the world, including the brains at The University of Manchester and the Max Planck Institute for Radio Astronomy in Germany, have stumbled upon an unknown object in the Milky Way. The newly discovered object is heavier than the heaviest neutron stars we know. And lighter than the lightest black holes we’ve seen. The team used the MeerKAT Radio Telescope, to spot this mysterious object. This celestial entity is in orbit around a high-speed millisecond pulsar, situated around 40,000 light years away in…

Astronomers Pinpoint Oldest Known Black Hole: Time-Traveling with Telescopes

Recently, astronomers have detected a super-old black hole, which is devouring its galaxy. It is dated back to the earliest black hole ever. It’s like the ultimate space buffet for the oldest black hole. Researchers at the University of Cambridge, unleashed the NASA/ESA/CSA James Webb Space Telescope (JWST) to spot this ancient black hole. The gravity well is chilling out 400 million years post-Big Bang, that is, over 13 billion years back.

M87 Black Hole Unveils Magnetic Brilliance in Spiraling Light

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!

Meteorites Unveiled as Earth’s Nitrogen Messengers

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.

Earth’s Electrons: Unexpected Contributors to Lunar Water Formation

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.
