Universe Today- There was Evidence for Europa’s Geysers Hiding in Plain Sight in Old Spacecraft Data From 1997

Jupiter’s moon Europa continues to fascinate and amaze! In 1979, the Voyager missions provided the first indications that an interior ocean might exist beneath it’s icy surface. Between 1995 and 2003, the Galileo spaceprobe provided the most detailed information to date on Jupiter’s moons to date. This information bolstered theories about how life could exist in a warm water ocean located at the core-mantle boundary.

Even though the Galileo mission ended when the probe crashed into Jupiter’s atmosphere, the spaceprobe is still providing vital information on Europa. After analyzing old data from the mission, NASA scientists have found independent evidence that Europa’s interior ocean is venting plumes of water vapor from its surface.

Universe Today- The Pressure Inside Every Proton is 10x That Inside Neutron Stars

Neutron stars are famous for combining a very high-density with a very small radius. As the remnants of massive stars that have undergone gravitational collapse, the interior of a neutron star is compressed to the point where they have similar pressure conditions to atomic nuclei. Basically, they become so dense that they experience the same amount of internal pressure as the equivalent of 2.6 to 4.1 quadrillion Suns.

Universe Today- Are Mysterious Fast Radio Bursts Coming From the Collapse of Strange Star Crusts?

Fast Radio Bursts (FBRs) have fascinated astronomers ever since the first one was detected in 2007. This event was named the “Lorimer Burst” after it discoverer, Duncan Lorimer from West Virginia University. In radio astronomy, this phenomenon refers to transient radio pulses coming from distant cosmological sources, which typically last a few milliseconds on average.

Over two dozen events have been discovered since 2007 and scientists are still not sure what causes them – though theories range from exploding stars and black holes to pulsars and magnetars.

The Hill – Ted Cruz and Bill Nelson give NASA a reality check on privatizing International Space Station

Ted Cruz and Bill Nelson believe the Trump administration’s plan to privatize the ISS by 2025 is not happening. It is questionable whether a sufficient business case exists under which private companies can create a self-sustaining and profit-making business independent of significant government funding. In particular, it is unlikely that a private entity or entities would assume the Station’s annual operating costs, currently projected at $1.2 billion in 2024. Such a business case requires robust demand for commercial market activities such as space tourism, satellite servicing, manufacturing of goods, and research and development, all of which have yet to materialize.
