Sahara being one of the hottest and driest places on earth, where temperature reaches to 122 degrees Fahrenheit, witnessing snowfall is actually a rarity. The reason associated with thesnowfall in this region is because of cold air aloft associated with a surface storm drifting from Spain to northern Algeria. As per Meteorologist Jason Nicholls, “The cold pool of air coupled with precipitation from the surface storm led to precipitation falling as snow instead of rain. The same feature responsible for the snow over the Sahara brought the heavy snow to the Alps earlier this week.” Scientists are, however, not attributing this rare snowfall event to the climate change as extreme weather conditions might become more of a common thing in the future, as well as the climate changes

READ CAPTION How a Student Took a Photo of a Single Atom The award-winning long-exposure photograph captures a positively charged atom suspended in an ion trap. SOMETIMES, ALL IT takes to capture a great photo is a DSLR camera, a microscopic atom, and a curious Ph.D. candidate. David Nadlinger, who traps atoms for his quantum computing research at the University of Oxford, captured this image on August 7 using a standard DSLR camera. The photo shows a pinprick of a positively charged strontium atom illuminated by a blue-violet light on a black background. The atom is held nearly motionless by an electric field emanating from two metal electrodes placed on either side of it. The distance between the ion trap's small needle tips is less than .08 of an inch. The photograph, entitled "Single Atom in an Ion Trap," won the overall science photography prize put on by the UK's Engineering and Physical Sciences Research Council.

  Objects with mass are attracted to each other, this is known as gravity. Gravity keeps Earth and the other planets in our solar system in orbit around the Sun. It also keeps the Moon in orbit around Earth. Tides are caused by the rotation of the Earth and the gravitational effects of the Moon and Sun. Because marshas a lower gravity than Earth, a person weighing 200 pounds on Earth would only weigh 76 pounds on Mars. It is thought that newton’s theories on gravity were inspired by seeing an apple fall from a tree. While Newton’s older law of universal gravitation is accurate in most scenarios, modern physics uses alebert eiastein’s general theory of relativity to describe gravity. Acceleration of objects to due to the gravity on Earth is around 9.8 m/s2. If you ignore air resistance (drag) then the speed of an object falling to Earth increases by around 9.8 metres per second every second. The force of gravity 100 kilometres (62 miles) above Earth is just 3% less than at the Earth’s s

View of mount Fuji from the airplane above it. ✈️✈️⛰️⛰️❤️❤️ Fuji, hardly any of the mountain can be seen from the planes' windows. For flights departing from Haneda Airport, this applies to routes flying to such airports as Kumamoto and Oita airport. Depending on your flight path, you may be able to get a rare top-down view of Mt. Fuji from the left side of the plane. For more scientific fact and information follow @map_of_science_

 The Oh-My-God particle was an ultra-high-energy cosmic ray detected on 15 October 1991 by the Fly's Eye camera in Dugway Proving Ground, Utah, U.S. At that time it was the highest-energy cosmic ray that had ever been observed.Although higher energy cosmic rays have been detected since then, this particle's energy was unexpected, and called into question theories of that era about the origin and propagation of cosmic rays. The Oh-My-God particle's energy was estimated as (3.2±0.9)×1020 eV, or 51 J. This is 20 million times more energetic than the highest energy measured in electromagnetic radiation emitted by an extragalactic object.It had 1020(100 quintillion) times the photon energy of visible light, equivalent to a 140 grams (5 oz) baseball travelling at about 26 m/s (94 km/h; 58 mph). Assuming it was a proton, this particle traveled at 99.99999999999999999999951% of the speed of light, its Lorentz factor was 3.2×1011 and its rapidity was 27.1. At this speed, if a photon

 A magnetar is a type of neutron star believed to have an extremely powerful magnetic field(∼109 to 1011 T, ∼1013 to 1015 G).The magnetic field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays. The theory regarding these objects was proposed by Robert Duncan and Christopher Thompsonin 1992, but the first recorded burst of gamma rays thought to have been from a magnetar had been detected on March 5, 1979. During the following decade, the magnetar hypothesis became widely accepted as a likely explanation for soft gamma repeaters(SGRs) and anomalous X-ray pulsars (AXPs). On 1 June 2020, astronomers reported narrowing down the source of Fast Radio Bursts (FRBs), which may now plausibly include "compact-object mergers and magnetars arising from normal core collapse supernovae. 👉 follow  @map_of_science_
