New study reveals earth's inner core has stopped spinning and may be changing directionA new study has found that the Earth's inner core recently stopped rotating and reversed its spin direction. This is a significant discovery for our understanding of the Earth's inner dynamics and the interactions between its layers. The crust, mantle, and core make up the three groups of layers that make up the Earth. Through the study of seismic waves from earthquakes, the inner core, which is located at the planet's…

The Cassini probe snapped this picture of Saturn in 2007 from an orbit of around 700,000 miles (1.1 million kilometres) from the planet. Saturn's seasons are reflected in the length of the shadow. The ring-cast shadows shifted southward as the Earth approached its equinox in 2009. The next equinox on Saturn is predicted to occur on May 6, 2025, which is around 15 Earth years from now. The image also show the rings of Saturn. Saturn and its rings, a tawny colour, stand out against the blackness of…

Days after the uncommon green comet Comet ZTF (C/2022 E3) made its closest approach to the Sun, scientists noticed something out of the ordinary. It is expected that the uncommon green comet will be seen to the naked eye sometime in the first week of February as it makes its approach nearer Earth. Something strange is occurring to the comet's tail, and astronomers have discovered it is getting separated. It's separating now. Photographed by Austrian astronomer Michael Jaeger on January 17, the comet seemed to…

James Webb Telescope, NASA's latest space telescope, has taken some stunning pictures of our early universe since it was placed in orbit. It is the biggest optical telescope in orbit, and its excellent resolution and sensitivity mean it can see objects that are too ancient, far, or dim for the Hubble Space Telescope. To learn more about star formation in the early cosmos, scientists might look for local analogues. Because of this, the NGC 346 was studied by NASA's James Webb telescope, which uncovered…

Indian Space Research Organization (ISRO) plans to shift its focus from space applications to scientific studies in 2023 with the launch of the sun- and moon-specific missions Aditya and Chandrayaan-3, respectively, despite the expected growth of the young start-up industry. India's first manned space trip, the Gaganyaan project, will also begin a series of tests in 2023, with the first uncrewed mission scheduled for the fourth quarter of that year to verify the effectiveness of the launch vehicle, orbital…

Asteroid responsible for mass extinction of dinosaurs on Earth possibly caused megatsunami on MarsAn asteroid impact similar to the Chicxulub collision which resulted in the mass extinction of most dinosaurs on Earth, that occurred in a shallow ocean zone, was likely the origin of a megatsunami on Mars. In the past, scientists have hypothesised that a tsunami had occurred about three billion years ago as a result of an asteroid strike on a Martian ocean in the northern plains.  Researchers…

The year was 1737 and, due to the large diversity of plants and animals collected by naturalist explorers in different parts of the world, Linnaeus saw the need to develop a logical system to classify and group this material in a systematic way. It’s a system that’s stood the test of time – his basic formula is still in use. The naming convention applies to all biological organisms: plants, animals and bacteria. Each species receives a name…
