10 Little Known Facts About the Juno Mission

little known facts about juno

Juno is the second spacecraft designed under NASA’s New Frontiers Program and left Earth on August 8, 2011 for a journey to Jupiter.  July 4, 2016 it finally entered Jupiter’s orbit and will now orbit the massive gas giant 37 times in a span of 20 months.  Its mission: to collect data on the planetary core, map the magnetic field, and measure the amount of water and ammonia in the atmosphere.
That’s the gist of the mission, but here are some little known facts you may not already know.

Meet the Black Hole 21 Billion Times the Mass of Our Sun

It is believed that the black hole at the center of our own Milky Way Galaxy, Sagittarius A, is 4 million solar masses.  This is the the most massive object in our galaxy.  Even so, it is dwarfed in comparison with the black hole located at the center of NGC 4889, a galaxy 308 million light-years away at the center of the Coma Cluster.  This elliptical galaxy is one of the brightest and largest galaxies in the Coma Cluster, and even though it doesn’t display much activity, it contains a black hole with a mass 21 billion times that of our Sun.

 Caltech scientists Konstantin Batygin and Mike Brown make the case for Planet Nine, a giant planet tracing a bizarre, highly elongated orbit in the outer solar system.

The Most Violently Explosive Supernova so Far Detected

Supernovae are some of the brightest events that happen in space.  However, in recent decades scientists have discovered a rare new class of blasts known as superluminous supernovae (SLSNe), or “hypernovae” to some.  The new discovery was spotted last June by the All Sky Automated Survey for SuperNovae (ASAS-SN).  At its peak, the new supernova known as ASAS-SN-15lh outshone our entire Milky Way galaxy by 50 times.

Why A Mysterious Dimming Star Doesn’t Mean Aliens

Dyson

For the past several days there has been a lot of talk about this mysterious star located some 1,480 light-years away called KIC 8462852, located in the constellation Cygnus .  This star appears to be flickering at irregular intervals.  Some have gone so far as to hypothesize that the dimming is a sign of an advanced alien presence, suggesting the possible presence of advanced satellite orbits or a Dyson sphere.  This has been a hot news story in the reaches of astronomy.  But I waited to post anything about it, choosing not to jump on the train of speculation until further news came in.

Did Stephen Hawking Crack the Information Paradox to Black Holes?

On Tuesday, renowned physicist Stephen Hawking presented his new theories on black holes to a gathering of esteemed scientists and members of the media at KTH Royal Institute of Technology in Stockholm.  Hawking focused on something called the information paradox, an aspect of black holes that has been puzzling scientists for years. Basically, the paradox involves the fact that information about the star that formed a black hole seems to be lost inside it, presumably disappearing when the black hole inevitably disappears. However, according to how the universe works and what physicists believe, these things cannot be lost. But where does the information go when the black hole that’s absorbed goes down the drain?
