A grain of dust collected from an ancient meteorite found in Antarctica has brought to light some incredibly fascinating revelations about our universe. This tiny speck, known as olivine, has a composition that defies our expectations, pointing towards an extraterrestrial origin. Isotopic analysis of this grain has indicated that it could only have been formed

The recent revelation of the magnetic fields spiraling around the supermassive black hole Sagittarius A* has provided fascinating insights into the nature of these cosmic giants. By analyzing the effect of polarization in a direct image of the shadow of Sgr A*, scientists have uncovered a magnetic field structure that bears striking similarity to the
The International Space Station (ISS) has been a critical asset for scientific research and human exploration in space. However, it won’t last forever, leading NASA to invest heavily in potential replacements. One of the most promising candidates is Orbital Reef, a joint venture between Blue Origin and Sierra Space. Recently, NASA announced that Orbital Reef
Mars, often referred to as the “Red Planet,” is covered in numerous impact craters, a stark contrast to Earth. This stark difference can be attributed to the absence of weathering forces and strong plate tectonics which disrupt the formation of such impact craters on our home planet. However, it is important to note that not
Discovering the origins of the Universe has always been a fascinating subject for astronomers. A recent search for the first stars that emerged during the early days of the cosmos has led to the discovery of one of the oldest stars observed to date. This ancient star, known as LMC 119, was found in the
As we look up at the night sky, it’s easy to forget just how small we are in the grand scheme of the universe. The Earth orbits an average star, our Sun, which in turn orbits the centre of our Galaxy, the Milky Way. But beyond this familiar territory lies a vast and mysterious landscape.
Recent discoveries have shed light on two streams of ancient stars within the Milky Way, believed to be almost as old as the Universe itself. These celestial bodies, named Shiva and Shakti by astrophysicist Khyati Malhan and astronomer Hans Walter-Rix, provide a glimpse into the early stages of our galaxy when it was still in
The stability of planetary systems has long been a topic of interest for physicists and astronomers alike. While we have a good grasp on the rules governing the orbits of two celestial bodies, the introduction of a third (or more) adds a level of complexity that leads to unpredictable instabilities. This so-called “three-body problem” has
A cosmic event of epic proportions is on the horizon, as a nearby star is gearing up to burst in a massive explosion known as a nova. Situated 3,000 light-years away from Earth, this spectacular show is expected to outshine even our North Star. The event is anticipated to be so grand that it will
The idea of the Universe being 13 billion years older than currently believed challenges the very foundation of cosmology. The proposal put forward by theoretical physicist Rajendra Gupta suggests that the Universe’s age has been misrepresented due to the tricks played by light. This challenges the existing notion of dark matter and dark energy, two
Exploring the mysteries of Mars has always been a fascinating subject for scientists. In a recent discovery, researchers have unearthed a massive, ancient volcano hidden beneath the region known as Noctis Labyrinthus. This finding has sparked new interest in the equatorial site as a potential location for uncovering clues about the planet’s past, particularly in
Our Solar System is not an isolated entity in the vastness of space. It was born within a stellar nursery, surrounded by hundreds of sibling stars and interstellar objects. Over time, these interactions have shaped our understanding of the cosmos and prompted researchers to search for traces of interstellar material on Earth. Recently, a study
