Power in Perspective

Power in Perspective

Oct 12, 2018 What astronomers call a “Fast Radio Burst” can release more energy in five milliseconds than the Sun does in 80 years! Assumed distances to such high energy sources is said to be a billion light-years, or more, because of redshift measurements. If that is the case, then ...

Ionized Moon

Oct 11, 2018 Phobos could be electrically charged. Of the two Martian moons, Phobos is the largest, at 28 by 20 kilometers. Its most prominent feature is Stickney crater, a ten-kilometer-wide excavation that is almost as large as Phobos, itself. If the crater was caused by the impact of an ...

Oct 10, 2018 The Parker Solar Probe is beginning its seven year maneuvering phase. The Parker Solar Probe was launched on August 12, 2018. Its first gravity assisted slow-down took place on October 3, 2018. The probe will conduct several more gravity-assist maneuvers with Venus over the course of the ...

Oct 9, 2018 Recent information reveals new dwarf planet features. The Kuiper Belt theory was proposed by astronomers Kenneth Edgeworth and Gerard Kuiper in 1951. Sometimes known as “trans-Neptunian Objects”, scores of Kuiper Belt Objects (KBO) from the size of small moons to the size of small planets are now ...

Deep in the Dark

Oct 8, 2018 The Universe keeps getting bigger. A recent press release announced that astronomers, combining data from the Hubble Space Telescope and the Spitzer Space Telescope, found a galaxy they believe is 13.3 billion light-years from Earth, making it the most distant object ever detected. According to the report, ...

Electrical Dynamism

Electrical Dynamism

Oct 5, 2018 More Cassini data analysis. Saturn’s magnetosphere is an electrical environment, causing dark-mode plasma discharges and lightning bolts that flash across the ring plane. As previously written, when Cassini entered orbit around the giant planet, mission specialists were shocked to discover lightning of immense power, up to a million times more powerful than anything ...

A Burst in the Night

A Burst in the Night

Oct 3, 2018 Many phenomena could be due to something astronomers do not expect. Some things are familiar, even though they are not easily explained. The aurorae at each of Earth’s poles are familiar to most people, although the way they form is not completely understood. Similarly, lightning bolts are ...

Oct 3, 2018 Stars are not neutral entities existing in a medium that isolates them from one another. In an Electric Universe, stars are not powered by hydrogen fusion, but by incoming electric charge. If any fusion takes place, it is not in the core, but in the stellar photosphere, ...

Earth's Electric Fields

Earth’s Electric Fields

Oct 2, 2018 Magnetic reconnection does not drive electromagnetic events. Upper regions of Earth's atmosphere are influenced by solar emissions, because the ionosphere is connected to the Sun by filaments of electric charge. At 150 kilometers altitude, Earth’s electromagnetic field exhibits the greatest conductivity in what is called the “dynamo ...

Oct 1, 2018 A ring of gas and stars is said to be orbiting the Milky Way. Galaxies are mysterious. Astronomers are still not sure if they are a rotating collection of individual stars held together by gravity, or if they are a discrete object, behaving as a whole. Consensus ...

So Hot You're Cool

So Hot You’re Cool

Sep 28, 2018 Hot spots on the gas giant planets are really very cold. NASA scientists have been puzzled by Saturn's hot north pole, although the term “hot” is relative. The average temperature at the pole is around minus 200 Celsius. The northern latitudes of Saturn were hidden from the ...

Recent Arrival

Sep 27, 2017 Martian meteorites are most likely a few thousand years old, at most. The Martian lithosphere is composed of iron and silicon, although they are primarily bound with oxygen. Silicon dioxide and iron oxides are the main constituents of Martian regolith. The atmospheric density on Mars is 0.6% ...

Gassy Dust

Sep 26, 2018 Methane dust on Titan? NASA launched the Cassini-Huygens mission on October 15, 1997. The six ton orbiter was the largest satellite ever deployed, entering orbit around Saturn on June 30, 2004. Its name was changed twice during its run: Cassini Equinox Mission on July 1, 2008, following ...

Sep 25, 2018 The search for water on Mars continues. According to a recent press release, Mars may not possess the large quantities of water-ice that previous observations suggested. Data provided by the Mars Express orbiter points to, "ice-free, porous, windblown sand" and not subsurface ice. Thomas R. Watters, a ...

Landers Away!

Landers Away!

Sep 24, 2018 Five surface instruments are scheduled for Ryugu. The Hyabusa 2 spacecraft is orbiting asteroid 162173 Ryugu, where, on September 21, 2018 it released two landers. Known as MINERVA-II, they "hop" from place-to-place on the surface. Since Ryugu's gravity field exerts a mere .00012 m/s² acceleration (80,000 times ...

Sep 21, 2018 Jupiter generates its own power. On August 5, 2011 NASA launched the Juno mission to Jupiter. It is currently analyzing Jupiter’s massive plasmasphere, along with its electromagnetic field. Jupiter radiates more energy in the infrared than it receives from the Sun, so astronomers think that it is ...

Sep 20, 2018 Reflective mineral deposits on Ceres. NASA launched the Dawn spacecraft on September 27, 2007. After its observations of the asteroid, Vesta ended on September 5, 2012 Dawn headed toward Ceres. Dawn encountered the largest known asteroid in the Solar System on March 6, 2015. The mission officially ended in ...

Dawn’s Twilight

Sep 19, 2018 The mission is winding down. On September 27, 2007 NASA launched the Dawn spacecraft. After observing the asteroid Vesta, Dawn headed toward Ceres. Dawn encountered the largest known asteroid on March 6, 2015, where it remains in orbit. The mission officially ended in June of 2016, but was ...

Black Ideas

Sep 18, 2018 Black holes are said to "warp space". Consensus theories state that inside of a black hole matter occupies no volume, yet retains its gravitational forces. Those forces are so great that no light can escape, so they are called "black" holes, because they are undetectable with optical ...

Still Life on Titan

Sep 17, 2018 Cold and dark. On October 15, 1997 NASA launched the Cassini-Huygens spacecraft. The six ton payload was the largest space mission ever deployed at the time, arriving at Saturn on June 30, 2004. Its name was changed twice during the mission: the Cassini Equinox Mission was a ...

Sep 14, 2018 Galaxies are alive with lightning flashes. "Bring in the bottled lightning, a clean tumbler, and a corkscrew." --- Charles Dickens On Earth, a primary electric discharge channel is called a lighting bolt. In slow-motion, it is easy to see that each flash is a complex series of ...

Sep 13, 2018 A captured moon? Neptune's moons do not fit into an orderly arrangement. Nereid's orbit takes it so far out at aphelion that it almost escapes Neptune's gravity. Most of Neptune's moons are not visible from Earth and there is little known about them. About half are so ...

Sep 12, 2018 Neutron stars cannot exist. "The sky was clear—remarkably clear—and the twinkling of all the stars seemed to be but throbs of one body, timed by a common pulse." ---Thomas Hardy On June 13, 2012 NASA launched the Nuclear Spectroscopic Telescope Array (NuSTAR) on a mission to study ...

Cosmic Electromagnetism

Sep 11, 2018 The Universe is not only in motion. Galactic evolution occurs because large-scale plasma discharges form coherent filaments that exhibit electrodynamic behavior. Since the Universe is an electrical system that is constantly charging and discharging, instead of a gravitational system that is constantly contracting and expanding, gravity is not ...

Ring in the True

Sep 10, 2018 Black holes do not power this ring of stars. Astronomers recently discovered what they believe to be a "ring of black holes or neutron stars" in galaxy AM 0644-741, located 300 million light years away. Observations from the Chandra X-ray Observatory are said to reveal stellar-mass black ...
