Ghost of Comet ISON Fading Fast

Comet ISON—or whatever is left of it—is fading fast, and the latest images from the NASA/ESA Solar and Heliospheric Observatory (SOHO) LASCO-C3 camera may be showing [...]

Ghost of Comet ISON Rises Like an Icy Phoenix After Suicidal Kamikaze Visit With the Sun

ISON appears as a white smear heading up and away from the Sun. ISON was not visible during its closest approach to the Sun, so many scientists thought it had disintegrated, but images like this one from the ESA/NASA Solar and Heliospheric Observatory suggest that a small nucleus may be intact.

All Eyes on Comet ISON as It Plummets Toward Thanksgiving Day Brush With the Sun

VIDEO: Comet ISON moves ever closer to the Sun in this movie from the ESA/NASA Solar and Heliospheric Observatory, captured in the early hours of Nov. 27, 2013. A coronal mass ejection explodes off the Sun; it is unlikely to damage ISON even if they cross paths. Image Credit/Caption: ESA/NASA/SOHO

Comet ISON Appears In Tact As it Plunges Toward Perihelion Next Month

NASA’s Hubble Space Telescope captured this image of Comet ISON on Oct. 9, 2013. The image suggests that the comet is intact, a good sign that it will survive perihelion next month when it dives to within one million miles of the Sun’s surface.

Chris Hetlage with Imaging the Cosmos offers up another stunning array of images from his observatory at the Deerlick Astronomy Village in Georgia. This dark sky community has produced stunning imagery of the majesty of space. This collection of photos contain images [...]

IBEX Sees Our Solar System's 'Tail'

Three years of observations by NASA’s Interstellar Boundary Explorer (IBEX) have shown that the Solar System has a tail shaped like a four-leaf clover. The stream of particles that blows away from the Sun, known as [...]

NASA Official Clarifies Voyager 1 Announcement

The Voyager 1 spacecraft has entered into a region of space known as the “magnetic highway.” It is one step closer to reaching interstellar space; but it still has a ways to go. Image Credit: NASA / JPL-Caltech

With a topic as complex as space exploration, confusion sometimes follows. Such has been the case [...]

The Moon and Sun

Image Credit: NASA/SDO/LRO/GSFC

Two or three times a year, NASA’s Solar Dynamics Observatory observes the Moon traveling across the Sun, blocking its view. While this obscures solar observations for a short while, it offers the chance for an interesting view of the shadow of the Moon. The Moon’s crisp horizon can be seen up [...]
