Sun-observing spacecraft sheds light on the solar wind''s origin

Picoflare jets

  • These small-scale picoflare jets were observed within emissions from the coronal hole under observation.
  • They lasted only a few dozen seconds, scientists calculated that they provide enough energy to supply a considerable fraction of solar winds.
  • These jets from the sun are named so because they carry approximately one-trillionth the energy of the largest flares the sun is capable of producing,
  • Significance:
    • The discovery is important because strong gusts of solar winds, while creating beautiful auroras in polar areas, are capable of disrupting the earth’s magnetic field as well as damaging electronics in satellites in space and in circuits on the ground.

Solar Orbiter Aircraft

  • It was launched in 2020 and will take images of the Sun from closer than any spacecraft before.
  • It contains six remote-sensing instruments and four sets of in situ instruments.
  • Objectives
    • To observe the Sun’s 11-year cycle of rising and subsiding magnetic activity.
    • To study the upper layer of its atmosphere, the corona.

Paleontologists Uncover New Species of Titanosaur in Egypt

Igai semkhu

  • It belongs to a diverse group of long-necked plant-eating dinosaurs called Titanosauria.
  • Igai semkhu roamed the earth during the Campanian age of the Late Cretaceous epoch, approximately 75 million years ago.
  • The group is known for large body sizes, long necks and wide stance. It includes species ranging from the largest known terrestrial vertebrates to ‘dwarfs’ no bigger than elephants.
  • Igai semkhu constitutes one of the most informative dinosaurs yet recovered from the latest Cretaceous of Afro-Arabia.

Cretaceous epoch

  • It is the third and final period of the Mesozoic Era, which is often referred to as the "Age of Dinosaurs."
  • The Cretaceous Epoch lasted from approximately 145 million years ago to about 66 million years ago, making it one of the longest geological epochs.
  • Mass Extinction:
    • The Cretaceous-Paleogene (K-Pg) mass extinction event marks the end of the Cretaceous Epoch.
    • It occurred around 66 million years ago and resulted in the extinction of approximately 75% of Earth''s species, including the non-avian dinosaurs.
    • This event is believed to have been triggered by a combination of factors, including the impact of a large asteroid or comet and massive volcanic activity.
