My kids (12&7) are very interested in astronomy right now. Any suggestions for educational websites that aren't watered down and boring but also won't be over their heads?

Google Maps for the Sky

Google certainly has an expertise in mapping, and that skill set even extends to the sky. You might be surprised to learn that Google actually has a Google Maps version for the sky. The site allows users to view constellations, planets and anything else a burgeoning or hobbyist astronomer might want to explore.

"Google Sky Map" is an Android app for smartphones

"Google Sky" is a browser-based astronomy app

A team of astronomers from the University of Manchester, the Max Planck Institute for Radio Astronomy and the University of Bonn have uncovered a hidden stellar birthplace in a nearby spiral galaxy, using a telescope in Chile. The results show that the speed of star formation in the centre of the galaxy - and other galaxies like it - may be much higher than previously thought.

M13: A Great Globular Cluster of Stars
Image Credit & Copyright: Dean Fournier; Inset: +European Space Agency, ESA/Hubble & +NASA
http://apod.nasa.gov/apod/ap160727.html

M13 is one of the most prominent and best known globular clusters. Visible with binoculars in the constellation of Hercules, M13 is frequently one of the first objects found by curious sky gazers seeking celestials wonders beyond normal human vision. M13 is a colossal home to over 100,000 stars, spans over 150 light years across, lies over 20,000 light years distant, and is over 12 billion years old. At the 1974 dedication of Arecibo Observatory, a radio message about Earth was sent in the direction of M13. The featured image in HDR, taken through a small telescope, spans an angular size just larger than a full Moon, whereas the inset image, taken by Hubble Space Telescope, zooms in on the central 0.04 degrees.

Gorgeous 180 degree panorama of our home, the Milky Way. Not without many other close cosmic neighbors however. LMC and SMC, Andromeda, Mars, Jupiter, Saturn, Comet. Nice.

At the NASA Advisory Council Human Exploration and Operations Committee Meeting on Monday, Bill Gerstenmaier, the associate administrator for HEO at the agency, said he believes we could have astronauts make it to Martian orbit — or conduct a short-distance flyby of the red planet — by 2033. According to current budgets and plans, the …

Cassiopia A - Glowing remains of an old supernova

Glowing gaseous streamers of red, white, and blue — as well as green and pink — illuminate the heavens like Fourth of July fireworks. The colorful streamers that float across the sky in this photo taken by NASA's Hubble Space Telescope were created by one of the biggest firecrackers seen to go off in our galaxy in recorded history, the titanic supernova explosion of a massive star. The light from the exploding star reached Earth 320 years ago, nearly a century before our United States celebrated its birth with a bang.

The dead star's shredded remains are called Cassiopeia A, or "Cas A" for short. Cas A is the youngest known supernova remnant in our Milky Way Galaxy and resides 10,000 light-years away in the constellation Cassiopeia, so the star actually blew up 10,000 years before the light reached Earth in the late 1600s.

This stunning Hubble image of Cas A is allowing astronomers to study the supernova's remains with great clarity, showing for the first time that the debris is arranged into thousands of small, cooling knots of gas. This material eventually will be recycled into building new generations of stars and planets. Our own Sun and planets are constructed from the debris of supernovae that exploded billions of years ago.

This photo shows the upper rim of the supernova remnant's expanding shell. Near the top of the image are dozens of tiny clumps of matter. Each small clump, originally just a small fragment of the star, is tens of times larger than the diameter of our solar system.

This photo shows the upper rim of the supernova remnant's expanding shell. Near the top of the image are dozens of tiny clumps of matter. Each small clump, originally just a small fragment of the star, is tens of times larger than the diameter of our solar system.

The colors highlight parts of the debris where chemical elements are glowing. The dark blue fragments, for example, are richest in oxygen; the red material is rich in sulfur.

The star that created this colorful show was a big one, about 15 to 25 times more massive than our Sun. Massive stars like the one that created Cas A have short lives. They use up their supply of nuclear fuel in tens of millions of years, 1,000 times faster than our Sun. With their fuel exhausted, heavy stars begin a complex chain of events that lead to the final dramatic explosion. Their cores rapidly collapse, releasing an enormous amount of gravitational energy. This sudden burst of energy reverses the collapse and tosses most of the star's mass into space. The ejected material can travel as fast as 45 million miles per hour (72 million kilometers per hour).

White dwarfs, neutron stars and black holes. These were all theorized by physicists, and have all been discovered by observational astronomers. We know they’re out there.

Is that it? Is that all the exotic forms that stars can take? That we know of, yes, however, there are a few even more exotic objects which are still just theoretical. These are the quark stars. But what are they?

Cosmology  - 
 
Observing separate galaxies, their groups and clusters, we understand that the Universe is highly inhomogeneous on sufficiently small scales. At the same time, according to the cosmological principle, the Universe is supposed to be homogeneous and isotropic when viewed at a large enough scale. The natural question arises: what is this typical averaging scale, at which the cosmological principle comes into its own? The standard approach leads to the value ~ 370 Mpc, contradicting the fact of existence of the observed largest cosmic structures with Gpc dimensions. However, there is another suitable value in cosmology, which is 10 times larger at present, namely, the Yukawa range of gravitational interaction. Therefore, we can trust the cosmological principle starting from distances, which exceed ~ 3.7 Gpc, and then the contradiction associated with the Gpc structures may be removed.

The two potentially habitable earth like planets both seem to have dense, compact blankets of gas like those around Earth or Venus.
