Get the latest science news on important experiments, new discoveries and discoveries, from Chandrayaan-3 to detecting the inner layers of the Earth’s core.
ISRO has successfully completed important tests
The Indian Space Research Organization (ISRO) on Sunday said the lander for the Chandrayaan-3 mission had successfully conducted EMI-EMC tests on January 31 and February 2. According to the space agency, EMI-EMC testing is conducted for satellite missions. To ensure the functionality of satellite subsystems in the space environment and their compatibility with expected electromagnetic levels.
The James Webb Telescope discovers massive galaxies near the dawn of the universe
Astronomers have discovered what appear to be massive galaxies within 600 million years of the Big Bang, suggesting that the early universe may have had a stellar fast-track that created these “monsters”. While the new James Webb Space Telescope has identified even older galaxies dating to within just 300 million years of the universe’s beginning, it’s the size and maturity of these six apparent mega-galaxies that baffles scientists.
Scientists unlock secrets of Earth’s wickedly hot interior
An intensive study of Earth’s deep interior based on the behavior of seismic waves from large earthquakes has confirmed the existence of a distinct structure inside our planet’s inner core — a wickedly hot inner solid ball of iron and nickel about 800 miles (1,350 km) wide, researchers said Tuesday. In 2002 scientists proposed that hidden within this inner core was an inner part separate from the rest, similar to a Russian nesting matryoshka doll. The increasing sophistication of seismic monitoring has enabled this to be confirmed.
Study of bones transforms understanding of dinosaur growth
New research overturns a long-held belief that dinosaurs followed a uniform pattern in determining body size within a species, whether giant or miniature, with growth rate being the deciding factor. The researchers examined rings called cortical growth marks, which are placed annually inside the bones of three dozen theropod species — similar to growth rings inside tree trunks. Widely spaced rings indicate rapid growth rates. Closely spaced rings indicate slow growth. They found no general pattern based on body size. Some giant theropods grow rapidly and stop growing, and some grow slowly over a long period of time to reach the same size.
Scientists dissect 3,500-year-old bear discovered in Siberian permafrost
A brown bear almost perfectly preserved for 3,500 years in the frozen forests of eastern Siberia has been necropsied by a team of scientists after it was discovered by reindeer herders on a deserted island in the Arctic. Extreme temperatures helped preserve the bear’s soft tissue for 3,460 years, as well as the remains of its last recovery – bird feathers and vegetation. The bear is described as being 1.55 meters (5.09 ft) tall and weighing around 78 kg (12 stone). The Siberian scientific team skinned the bear, allowing scientists to examine its brain, internal organs and conduct numerous cellular, microbiological, virological and genetic studies.
India is likely to miss the deadline of 50% of the SDG indicators
India lags behind in achieving more than 50% of indicators under the UN’s Sustainable Development Goals (SDGs) seven years ahead of the 2030 deadline, a study has found. The Lancet Journal said. There are 17 SGDs for the security and prosperity of people and the planet, which 192 UN member states have committed to achieving by 2030. The study, which offers the first mid-line assessment of India’s progress towards the 2030 Agenda, measured progress across 9 goals by identifying 33 key indicators.
Maharashtra, Tamil Nadu among world’s top 50 regions at high risk due to climate change: Report
Nine of the world’s 50 regions face high climate risk for the collapse of fragile physical infrastructure in India, according to a new ranking released on February 20. Bihar (22nd), Uttar Pradesh (25th), Assam (28th), Rajasthan (32nd), Tamil Nadu (36th), Maharashtra (38th), Gujarat (48th), Punjab (50th) and Kerala (52nd) ) is the most vulnerable in the country, identifying the economic capital Mumbai as being at significant risk viz.
