  2. Parker Solar Probe - Wikipedia

    en.wikipedia.org/wiki/Parker_Solar_Probe

    Within each orbit of the Parker Solar Probe around the Sun, the portion within 0.25 AU is the Science Phase, in which the probe is actively and autonomously making observations. Communication with the probe is largely cut off in that phase. [57]: 4 Science phases run for a few days both before and after each perihelion. They lasted 11.6 days ...

  3. Millisecond pulsar - Wikipedia

    en.wikipedia.org/wiki/Millisecond_pulsar

    Gravitational waves are an important prediction from Einstein's general theory of relativity and result from the bulk motion of matter, fluctuations during the early universe and the dynamics of space-time itself. Pulsars are rapidly rotating, highly magnetized neutron stars formed during the supernova explosions of massive stars. They act as ...

    PSR J1748−2446ad is the fastest-spinning pulsar known, at 716 Hz (times per second), [2] or 42,960 revolutions per minute.This pulsar was discovered by Jason W. T. Hessels of McGill University on November 10, 2004, and confirmed on January 8, 2005.

    en.wikipedia.org/wiki/US_708

    In 2015, Stephan Geier of the European Southern Observatory led a team that reported in Science that the velocity of the star was 1,200 km/s (4,300,000 km/h; 2,700,000 mph), the highest ever recorded in the galaxy. [3] [7] [8] The star's high velocity was originally suspected to be caused by the massive black hole at the center of the galaxy.

  8. Accelerating expansion of the universe - Wikipedia

    en.wikipedia.org/wiki/Accelerating_expansion_of...

    Thus, an accelerating universe took a longer time to expand from 2/3 to 1 times its present size, compared to a non-accelerating universe with constant ˙ and the same present-day value of the Hubble constant. This results in a larger light-travel time, larger distance and fainter supernovae, which corresponds to the actual observations.

    Is the universe homogeneous and isotropic at sufficiently large scales, as claimed by the cosmological principle and assumed by all models that use the Friedmann–Lemaître–Robertson–Walker (FLRW) metric, including the current version of the ΛCDM model, or is the universe inhomogeneous or anisotropic?
