Astronomers discovered a rocket body heading toward a lunar collision late last year. Impact occurred on March 4, with NASA’s Lunar Reconnaissance Orbiter later spotting the resulting crater. Surprisingly the crater is actually two craters, an eastern crater (18-meter diameter, about 19.5 yards) superimposed on a western crater (16-meter diameter, about 17.5 yards). The double
As we know, the emergence of life requires three building blocks: an energy source, access to nutrition, and the presence of liquid water. Apart from these requirements, it remains unknown to what extent conditions on other planets need to resemble Earth to be habitable. But what if we search for planets that are different from
On Earth, many forces have combined to keep the conditions remarkably stable for millions of years. But other planets may not be so lucky. One of the scientists’ many questions about other planets is exactly how lucky we are—that is, how often this confluence exists in the universe. Studying what happened to other planets, such
Light is made of quantum particle photons, which have long been used to transmit and process information in today’s world. In the future also, it will play a crucial role in information processing in the future generation of quantum devices. But techniques to control the spectro-temporal properties of quantum states of light at ultrafast time
Bacteria are considered microscopic isolated cells or colonies. They are single microscopic cells with DNA free-floating in their cytoplasm. The size of the bacterial cells varies in size from 2 micrometers to the highest 750 micrometers. In a recent study, researchers have discovered a bacterium that challenges the prevailing view of bacterial cell size. The
Single photons are ideal carriers of quantum information, especially because they are fast, they barely interact with the environment or each other, and large-scale infrastructure for their distribution is already widely available. Now, before networks can really turn quantum, suitable quantum memories for single photons are needed. It is required for everything from buffering communication
Light gets distorted if you pass light through an imperfect medium, such as the atmosphere. For instance, the shimmering mirage effect near hot roads or the twinkling of stars are both examples of distorted light because of the atmosphere’s turbulence. Light can also sometimes be deliberately distorted, like the mirrors at a fun fair that
Growing global food demand is currently facing a major constraint of efficient energy conversion using photosynthesis. Photosynthesis has evolved in plants for millions of years to turn water, carbon dioxide, and the energy from sunlight into plant biomass and the foods we eat. Most crop plants can convert sunlight and CO2 into plant biomass at
A supernova is the cataclysmic explosion of a star. A thermonuclear supernova explosion of a white dwarf is supposed to be the terminal event in the life of its progenitor star. These thermonuclear supernovae, known as Type Ia supernovae, are some of the most important tools in astronomers’ toolkits for measuring cosmic distances. For a
The analysis of spiral galaxy rotation curves has empirically highlighted since the late 1970s -a discrepancy between the amount of luminous matter and the mass budget required to explain the overall kinematic properties of such systems. The common belief traces back the missing mass to an unseen component called dark matter, constituted by cold (i.e.
