Have
a stellar New Year
Blockbuster astronomy stories of 2016 include:
1. Confirmation
that invisible gravity waves exist, as predicted by Al Einstein a century
ago. Two complex detectors, one in
Louisiana and the other in Washington State, both picked up waves caused by the
merger of two black holes far out in the universe, and the findings became official
in 2016. Scientists across the globe hailed it as the discovery of the
generation.
2. The confirmed discovery
of a planet in the habitable zone around the closest star to us (other than our
own sun), Proxima Centauri, which floats just 4.2 light years away.
3. The spectacular
successes of reusable rockets from two energetic and innovative private space
companies, Blue Origin and SpaceX. The
technology will save millions of dollars in space exploration and satellite
launching and servicing.
4. The ambitious
Juno flight, the fastest spacecraft ever launched (165,000 mph), arrived at
Jupiter to begin its deep studies of that giant planet.
5. Startling
indications that there is a huge mysterious and yet-to-be-seen Planet Nine
circling our sun in a strange orbit.
And 2017 promises to be no less fascinating. The Quadrantid meteor shower will usher in
the year, peaking January third with an amazing 120 meteors per hour. But the big story will be a rare solar
eclipse, the sight of a lifetime. As the
moon moves in front of the sun, precisely covering its disc and cutting off all
its direct light, the whole sky will darken dramatically, revealing stars in
daytime. It’s a wondrous, magical,
deeply moving event. On August 21 the dense
shadow band of totality will carve a 70-mile-wide curved swath from the far
northwestern U.S., diagonally across the entire country and exiting through
South Carolina. Anywhere along that
route the viewing will be perfect.
You’ll need eye protection, though, and if you travel to that shadow
band, you’d better reserve accommodations early. You can get details online. Do not miss it.*
I hope you enjoy a stellar New Year in every way.

The moon can cover the sun because, although it is 400
times smaller than the sun, it is also 400 times closer to us.
