A New View of Kepler’s Supernova Remnant

KeplerNASA’s Chandra X-Ray Observatory has created this amazing image of one of the youngest supernova remnants in the galaxy. The supernova that created it blazed in the sky more than 400 years ago, before the telescope had even been invented. No problem, though, it was bright enough that you didn’t need a telescope – it reached the brightness of Jupiter at its peak. And one of the greatest astronomers in history, Johannes Kepler was there to see it.

Blizzard of Snowflake Particles Around a Young Star

Debris disk around AU Microscopii. Image credit: HubbleThe Hubble Space Telescope has imaged a ring of dust around a nearby star that will probably become a system of planets. The star is AU Microscopii, and it’s located about 32 light-years away in the southern constellation of Microscopium (the Microscope). The particles are probably as fluffy as snowflakes, and about 10 times larger than typical interstellar dust grains.

Use Galactic Gravitational Lenses to Really See the Universe

Galactic lens in action. Image credit: CFHTTo see any distance in space, you need some kind of telescope. We’ve got some pretty powerful ones here on Earth, but nature has us beat with gravitational lenses. This is a phenomenon when a relatively nearby object passes directly between us and a more distant object. The gravity from the nearby object acts as like a telescope lens to bend light and magnify the more distant object.
