To date, gravitational lenses have been hard to find, and only about a hundred are routinely used. Identified as a phenomenon by Einstein, gravitational lensing has been used by astronomers to observe far away galaxies for a long time, however, finding them in the first place has been hit and miss. The new study presents
More than 95 percent of Earth’s oceans have never been observed. MIT scientists have built a battery-free, wireless underwater camera to explore unknown ocean regions. The camera is about 100,000 times more energy-efficient than other undersea cameras and can capture color photos even in dark underwater environments, and transmits image data wirelessly through the water.
On Monday, Sept. 26, Jupiter will make its closest approach to Earth since 1963. Jupiter will be 367 million miles away from Earth when it makes its closest approach, which is around the same distance as in 1963. Rarely does Jupiter‘s closest approach to Earth coincide with its opposition, so this year’s views will be
Marine mammals are highly adapted to living underwater. One of the most challenging aspects of this environment is the extreme pressure that animals experience at increasing depth. This condition increases the need for brain protection from pulsatile blood flow, something experienced by all mammals. A new study by the University of British Columbia suggests that
Human blood type is determined by antigens on the red blood cells. An antigen is a structure on the cell surface that causes a human immune response reacts to if the structure is foreign to the person’s body. As a result, a blood type match is of critical importance. Most people are familiar with two
In December 2020, the Hayabusa2 spacecraft brought back the samples of the carbonaceous asteroid Ryugu to Earth. A new study sheds light on these samples; they discovered areas with a massive accumulation of rare Earth and unexpected structures. As part of international research collaboration, Geoscientist Professor Frank Brenker and his team from Goethe University Frankfurt
NASA/ESA Hubble Space Telescope has captured an image of a big, beautiful spiral galaxy called NGC 7331. Located almost 50 million light-years distant in the northern constellation Pegasus, the galaxy was recognized early on as a spiral nebula. It is actually one of the brighter galaxies not included in Charles Messier’s famous 18th-century catalog. The
A new study could allow scientists to create cyborgs at a cellular scale, thanks to MIT Media Lab for designing a miniature antenna that can operate wirelessly inside a living cell. This could have applications in medical diagnostics, treatment, and other scientific processes because of the antenna’s potential for real-time monitoring and directing cellular activity.
Since its discovery in 1846, the planet Neptune has been the topic of fascination for scientists. Neptune orbits in the remote, dark region of the outer solar system. The planet is also an ice giant because of its internal chemical composition. Its been three decades since scientists have observed Neptune rings. Now, NASA’s James Webb
