How to shoot photos of meteors, or shooting stars

Want to try to capture a meteor on film? The first step is planning. The next step is to gather your equipment. Then on to the capture process itself.

Comet Halley's position in May, 2016. The view is from the north side of the solar system, whereby the planets orbit the sun in a counterclockwise direction - but Halley's Comet orbits the sun clockwise. Click here for Comet Halley's present position, or if you'd like, change the date to view its position in any chosen year.

Comet Halley, parent of 2 meteor showers

The Eta Aquarid meteor shower was spawned by the famous Comet Halley. But Halley spawned another meteor shower, too.

A pure methane sea on Titan

We knew that Saturn’s moon Titan had seas and lakes of liquid hydrocarbons, but their exact composition was unknown until recently.

Shortest lunar month of 2016 starts May 6

Although the lunar month has a mean period of 29 days 12 hours and 44 minutes, the actual length varies throughout the year. Lengths of lunar months in 2016.

Just 40 light-years away, 3 potentially habitable planets

We don’t need to look for Earth-like planets exclusively around sun-like stars. Ultracool dwarf star TRAPPIST-1 hosts 3 potentially habitable Earth-sized planets.

Artist's impression of the unique object C/2014 S3 (PANSTARRS). Observations with ESO’s Very Large Telescope, and the Canada France Hawai`i Telescope, show that this is the first object to be discovered that is on a long-period cometary orbit, but that has the characteristics of a pristine inner Solar System asteroid. It may provide important clues about how the Solar System formed. Because the object has spent most of its life away from the inner Solar System it suffered very few collisions, and its surface displays few or no craters. As it formed in the same region as the Earth did, it is mostly rocky, and therefore has only very limited cometary activity.

Orbit like a comet, rocky like an asteroid

They’re calling it a Manx comet, after the cats with no tails. It may have formed in the inner solar system and been ejected outward.

Next Blue Moon is May 21, 2016

It’s a seasonal Blue Moon – an older definition of the term – the third of four full moons between the March equinox and the June solstice of 2016.

Mars rover crosses most rugged terrain so far

The Curiosity rover has nearly crossed a stretch of the roughest terrain it’s seen during its 44 months on Mars. Scientists are monitoring the wear and tear on the rover’s wheels.
