By July 2019, most astronomers concluded that it was a natural object, but its exact characterization is contentious given the limited observation window. While an unconsolidated object (rubble pile) would require ʻOumuamua to be of a density similar to rocky asteroids, [26] a small amount of internal strength similar to icy comets [27] would ...
In November 2017, the Space Telescope Science Institute announced the selection of 13 Director's Discretionary Early Release Science (DD-ERS) programs, chosen through a competitive proposal process.

In November 2013, astronomers reported, based on Kepler space mission data, that there could be as many as 40 billion Earth-sized planets orbiting in the habitable zones of Sun-like stars and red dwarfs within the Milky Way. 11 billion of these estimated planets may be orbiting Sun-like stars.
Leo (♌︎) ( Ancient Greek: Λέων, romanized : Léōn, Latin for "lion") is the fifth sign of the zodiac. It corresponds to the constellation Leo and comes after Cancer and before Virgo. The traditional Western zodiac associates Leo with the period between about July 23 and August 22, [2] and the sign spans the 120th to 150th degree of ...
The Kepler space telescope is a defunct space telescope launched by NASA in 2009 [5] to discover Earth-sized planets orbiting other stars. [6] [7] Named after astronomer Johannes Kepler, [8] the spacecraft was launched into an Earth-trailing heliocentric orbit. The principal investigator was William J. Borucki.
