I am on Pillowfort if my blog disappears tomorrow.

I doubt my blog with disappear, but just in case, the link is above. BTW I am participating in the Tumblr boycott, so I will be back on Tuesday.

A Solar Filament Erupts Image Credit: NASA’s GSFC, SDO AIA Team

Explanation: What’s happened to our Sun? Nothing very unusual – it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space producing an energetic Coronal Mass Ejection (CME). The filament had been held up for days by the Sun’s ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth’s magnetosphere, causing visible aurorae. Loops of plasma surrounding an active region can be seen above the erupting filament in the featured ultraviolet image. Although the Sun is now in a relatively inactive state of its 11-year cycle, unexpected holes have opened in the Sun’s corona allowing an excess of charged particles to stream into space. As before, these charged particles are creating auroras.

Here I come a across a massive Super-Jovian gas giant. The planet is close to the boundary line with a brown dwarf and has a mass of more than 11 times that of Jupiter. It orbits a hot B-Type star that is part of a binary system consisting of a B type main sequence star and a blue supergiant. The system is located just outside of a globular cluster.

Monstrous storms rage across the planet’s atmosphere, powered not just from the warmth of two luminous suns, but also from internally released heat. A well-structured ring system surrounds the planet along with 66 natural satellites, 6 of which larger than the planet Mercury, including 1 ocean moon larger than Earth that has its own ring system.

Space Engine System ID: RSC 5581-4-0-0-300 B3 to visit the planet in Space Engine.

Planet Stats:

Radius: 71,573.62 km (11.22 x Earth, 1.02 x Jupiter) Mass: 11.06 Jupiter Masses (3,515 x Earth) Orbital Distance: 11.43 AU Length of Year: 16.33 Years Length of Solar Day: 7 hours 56 mins Gravity: 27.90 g Temperature: 720 K (836°F) Atmosphere Composition:  92.7% Hydrogen, 6.88% Helium, 0.32% Methane, 0.10% Hydrogen Deuteride

Insight A System - Fourth Planet (Insight A-IV)

Insight A-IV is the fourth and largest planet orbiting Insight A. It is a large ice giant planet with a mass 41.38 times that of Earth and a diameter of 4.41 Earths. The planet has a hot atmosphere with a temperature of 297 F, which is dominated by hydrogen and helium. Additionally, a single large moon orbits the planet alongside 13 smaller asteroid-like satellites.

The planet orbits it’s sun at an average distance of 0.36 AU, completing an orbit once every 72.17 Earth Days. The planet is not tidally locked, but has a slow rotational rate of 288.70 Earth days, resulting in solar days that last 96.23 Earth days.

Another Earth-Like world I have come across in the Large Magellanic Cloud Galaxy. This one has two moons and a rather cold surface with lots of ice covered mountains.
