The solar system is made of the eight planets that orbit our sun it is also made of asteroids, moons, comets and lots, lots more. The sun has such powerful gravity it tries to pull the planets towards it. While the planets try to fly away in the end they are kind of in the middle floating around the sun. They are 140 moons that orbit the eight planets in the solar system. The moons don’t...

From the southern regions of the U.S., Omega Centauri peeks into view low in the south late tonight. It looks like a fuzzy patch of light, but it’s really a cluster of more than a million stars packed into a tight ball only about 150 light-years across. It’s 17,000 light-years away. In May/June, we bring you our special Summer Reading Issue, in which we recommend new books. We’ve got...

Both of these planets are currently retrograding, which means they appear to be moving backwards through the constellations.

Astronomers using the SOAR telescope at CTIO have discovered a spectacular extended jet from a young brown dwarf. While young stars are known to launch jets that extend over a light year or more, this is the first such jet from a brown dwarf. The discovery, made by a team that includes NOAO astronomers Cesar Briceno and Steve Heathcote, lends new insight into how substellar objects form. Read...

The total lunar eclipse was going to occur from about 5:30 to 6:30 on Wednesday morning. My alarm was set for 6:00, like usual, and the forecast was for perfectly clear skies. I was awake fifteen minutes before my alarm but patiently waited until six o’clock, because the only upstairs windows that face west where the eclipsed Moon was setting are in my children’s bedrooms. I was not awake...
