An article just published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on the history and future of the formation of Earth-like planets. A team led by Peter Behroozi of the Space Telescope Science Institute (STScI) used data collected by the Hubble and Kepler space telescopes to evaluate the rate of formation of the Earth-like planets. The conclusion is that only 8% of potentially habitable planets existed at the birth of our solar system.
The Hubble Space Telescope was used to create new maps of the planet Jupiter. Hubble’s Wide Field Camera 3 captured a series of images of the planet within the Outer Planet Atmospheres Legacy program. The aim is to produce new maps every year and in the case of Jupiter 10 hours of daily shooting made it possible to discover new phenomena including changes in the Great Red Spot.
The Hubble Space Telescope took a picture of the planetary nebula PK 329-02.2, also known as ESO 178-15 or Hen 2-150 and commonly called Menzel 2 (Mz 2) because it was discovered by the astronomer Donald Menzel in 1922. Distant little more 7,700 light years from Earth, it’s visible in the constellation Norma and is another case in which a planetary nebula offers a breathtaking show, in this case with a blue cloud that aligns with the two stars at its center.
An article just published in the journal “Nature” describes the discovery of mysterious ripples across the disk of dust surrounding the star AU Microscopii, or AU Mic. Through SPHERE, an instrument mounted on ESO’s Very Large Telescope, a team led by Anthony Boccaletti, LESIA (Observatoire de Paris/CNRS/UPMC/Paris-Diderot), France, discovered these structures never seen before and yet to be explained.
The Indian government has signed the agreement that allows the country into the SKA Organisation and will from now on be fully involved in the development of the SKA radio telescope. India joins Australia, Italy, Netherlands, New Zealand, South Africa and the United Kingdom in the task of the SKA into an intergovernmental organization with a treaty to formalize the relationship between the project and its members.
