In the early morning hours of Thursday, an asteroid that is larger than two football fields will fly by the planet Earth (Aug. 4). At precisely 12:23 in the morning, the asteroid will go by (ET). Only a few days ago, on July 26, astronomers from NASA identified the asteroid that is now known as 2022 OE2. The meaty space rock is predicted to measure between 170 and 380 metres
According to fossils recently found in France, a pre-dinosaur species resembled a rotund lizard with a small head and a semiaquatic existence. The amphibian represents a previously unknown genus and species of mammalian ancestor, researchers stated in October’s Palaeo Vertebrata. Lalieudorhynchus gandi lived 265 million years ago on Pangaea, before dinosaurs. Fossils of the strange species were initially discovered in 2001 in the Lodève Basin in southern France by research
A constellation of more than 20 massive radar antennas will be used to gather data on potential rock-borne threats. An array of more than 20 massive radar antennae has begun construction at a renowned Chinese university to track asteroids that could be damaging to Earth. It’s called China Fuyan (or “composite eye”), and the Beijing Institute of Technology is leading it. Asteroids within 93 million miles (150 million kilometres) of
Any form of energy that is produced using natural resources like sunshine, wind, or water is considered to be a form of green energy. The term “green energy” is often used interchangeably with “renewable energy,” but there are a few key distinctions between the two that we will go over in the next section. The fact that these forms of energy don’t cause damage to the environment by doing things
Starlink satellite Internet service has been approved by the US government for use on moving vehicles, ships, and planes. The FCC on Thursday approved SpaceX’s proposal to operate ESIMs (Earth Stations in Motion) in the United States for both consumers and businesses. The FCC also granted Kepler Communications’ request to operate ESIMs on ships. As of now, ships in US territorial waters and international waters can use Starlink or Kepler.
Since the first successful preparation of graphene by mechanical exfoliation from graphite crystals in 2004, 2D materials have attracted dramatic attention due to their extraordinary physical properties (ultralow weight, high Young’s modulus, and high strength) and electrical properties compared with conventional bulk materials. Graphene, with a Young’s modulus of 1 TPa, is the most researched 2D material. Studies suggest that graphene in polymer matrices can boost composites’ mechanical characteristics. Graphene’s
Food security throughout the world may benefit greatly from hybrid agricultural and horticulture crops. Compared to non-hybrid cultivars, hybrids provide better yields and are frequently more resistant to disease and climatic stress. However, hybrid variants aren’t accessible for all crops. Global food security may benefit from the use of horticultural and hybrid crops. These hybrid cultivars produce more with a given acreage and are more resistant to pests and disease
Scientists at Nanyang Technological University have invented a novel waterproof and stretchy fabric that transforms energy generated by bodily movement into electrical energy. Nanyang Technological University. Mechanical energy is converted to electrical energy by pressing or squashing a polymer component of the cloth. Flexible, robust, and waterproof properties are all provided by a base layer of spandex combined with a rubber-like substance. Proof-of-concept testing of the fabric in Advanced Materials
James Webb Space Telescope and its collaborative NASA, ESA, and CSC teams have been working toward completing the six-month-long commissioning phase at Sun-Earth Lagrange point 2 since May. (L2). Now that the observatory’s mirrors have been perfectly aligned, Webb and its team are getting ready for the historic first image to be taken from their telescope. First scientific study objectives for Webb’s operational phase have been disclosed as teams move
Our ability to grasp the complexities of non-Earthly settings is limited. Astronomers have to deal with this problem all the time. Sometimes it’s only a matter of finding out how well-understood physics relates to severe situations and then comparing the output of those equations to the actual data. Neutron stars, on the other hand, are a remarkable exception to this rule, as the necessary equations become fully intractable and observations
