Light is energy that can take on many forms. Radio waves, microwaves, infrared, visible, ultraviolet, X-ray and gamma radiation are all different forms of light. (Illustration: NASA/CXC/M.Weiss)

Thackary's Globules. Located  in rich star fields & hydrogen gas, these opaque clouds of interstellar dust & gas are so large they might be able to form stars. They are located in IC 2944, a bright stellar nursery about 5900 ly away toward the constellation Centaurus. The largest of these dark globules, first spotted by S African astronomer A. D. Thackeray in 1950, is likely two separate but overlapping clouds.

These are larger dust bunnies than you will find under your bed. Situated in rich star fields and glowing hydrogen gas, these opaque clouds of interstellar dust and gas are so large they might be able to form stars. Their home is known as IC a bright

NGC 1300 by Steven Marx          A barred spiral galaxy about 61 million light-years away in the constellation Eridanus. The galaxy is about 110,000 light-years across; just slightly larger than our own galaxy, the Milky Way. It is a member of the Eridanus Cluster, a cluster of 200 galaxies. [**]

What if the other planets were as close as the Moon?

Pretty good as far as scale goes, but even Saturn and Jupiter would look quite larger, considering their size compared to Earth.

Long-term fans will know that images like this are my favourite.  Anything that gives us a sense of exactly how tiny we are in the universe makes me shiver. But do we really have a sense of it?

Como nossa terra é pequena no Universo. Aren't we tiny? can you even imagine the proportions? science and nature

Beautiful Wavelengths of Solar flare.  The first moments of a solar flare, captured at different wavelengths.

On Feb. the sun emitted a significant solar flare, peaking at p. NASA's Solar Dynamics Observatory (SDO), which keeps a constant watch on the sun, captured images of the event.
