Relevance: Science and technology

Context: when the moon comes between Earth and Mars, people will be able to see Mars, which is seen as a red dot in the night sky, next to the moon. The phenomenon known as occultation can be seen with naked eyes.

  • An occultation is an occurrence when one object is hidden from the observer by another object. This term is frequently applied in astronomy, but also in any situation in which the object in the foreground blocks an object in the background (occults).
  • If the closer body does not entirely conceal the farther one, the event is called a transit. Both transit and occultation may be referred to generally as occlusion; and if a shadow is cast onto the observer, it is called an eclipse.
  • Occultations led to the discovery of planet Uranus’ rings by Nasa’s Kuiper Airborne Observatory when the planet occulted a star. Moon-Mars occultations are visible from Earth twice a year.

Relevance: Science and technology

Context: Astronomers have discovered a dozen quasars that have been warped by a naturally occurring cosmic “lens” and split into four similar images.

More about Quasar

  • A quasar (also known as a quasi-stellar object, abbreviated QSO) is an extremely luminous active galactic nucleus (AGN), in which a supermassive black hole with mass ranging from millions to billions of times the mass of the Sun is surrounded by a gaseous accretion disk.
  • As gas in the disk falls towards the black hole, energy is released in the form of electromagnetic radiation, which can be observed across the electromagnetic spectrum.
  • The power radiated by quasars is enormous; the most powerful quasars have luminosities thousands of times greater than a galaxy such as the Milky Way.
  • High-resolution images of quasars, particularly from the Hubble Space Telescope, have demonstrated that quasars occur in the centres of galaxies and that some host galaxies are strongly interacting or merging galaxies.
  • Till now More than a million quasars have been found. The nearest known quasar is about 600 million light-years away (Markarian 231).
  • This rare discovery increases the number of known quasars or quads by about 25% and can help determine the expansion rate of the universe and address other mysteries.
