Winter Solstice 2018 Coincides With Both A Full Moon And Meteor Shower

Posted by in category: space

The winter solstice, falling on December 21, 2018, will mark the shortest day of the year as well as a full moon in the night sky. The upcoming full moon named the Cold Moon or the Long Night Moon will be visible during the longest night of the year.

The two events don’t perfectly align. The peak full Moon will occur on December 22 at 12:49 p.m. EST while the winter solstice falls a day earlier on December 21. However, to the typical person viewing the moon, it will appear full for several days.

The winter solstice marks a transition period where days begin getting longer in the Northern Hemisphere and shorter in the Southern Hemisphere. The evening of the winter solstice will be the longest of the year for the Northern Hemisphere. This is because Earth’s poles create a maximum tilt away from the Sun in the Northern Hemisphere and maximum tilt toward the Sun in the Southern Hemisphere.

New Horizons spacecraft takes the inside course to Ultima Thule

Posted by in category: space

With no apparent hazards in its way, NASA’s New Horizons spacecraft has been given a “go” to stay on its optimal path to Ultima Thule as it speeds closer to a Jan. 1 flyby of the Kuiper Belt object a billion miles beyond Pluto – the farthest planetary flyby in history.

NASA research reveals Saturn is losing its rings at ‘worst-case-scenario’ rate

Posted by in categories: particle physics, space

New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 & 2 observations made decades ago. The rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn’s magnetic field.

“We estimate that this ‘ rain’ drains an amount of water products that could fill an Olympic-sized swimming pool from Saturn’s rings in half an hour,” said James O’Donoghue of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “From this alone, the entire ring system will be gone in 300 million years, but add to this the Cassini-spacecraft measured ring-material detected falling into Saturn’s equator, and the rings have less than 100 million years to live. This is relatively short, compared to Saturn’s age of over 4 billion years.” O’Donoghue is lead author of a study on Saturn’s ring rain appearing in Icarus December 17.

This Breathtaking Image Is a Real Photo of Two Stars Destroying Each Other

Posted by in category: space

The death of a binary star can be a spectacularly violent thing.

This picture shows the binary system R Aquarii, a red giant throwing off its outer envelope, which is being greedily cannibalised by its companion, a much smaller, denser white dwarf.

The dramatic moment you’re looking at unfolded just 650 light-years from Earth – practically right next door in astronomical terms, which is why astronomers have a keen interest in the event.
