Followed by a moon shadow: 1989 Neptune images from Voyager 2 reviewed 20 years later

[CLICK ON IMAGE FOR HIGH RESOLUTION,  NASA, JPL – Processed Image Copyright: Ted Stryk] Despina is a tiny moon of Neptune … discovered in 1989, in images from the Voyager 2 spacecraft taken during its encounter with the solar system’s most distant gas giant planet. But looking through the Voyager 2 data 20 years later, […]

Nearby M7 star cluster stands out in a sea of … stars, farther away at our galaxy’s center

Nearby M7 star cluster stands out in a sea of … stars, farther away at our galaxy’s center

[CLICK ON IMAGE FOR HIGH RESOLUTION, Lorand Fenyes] M7 is one of the most prominent open clusters of stars on the sky. The cluster, dominated by bright blue stars, can be seen with the naked eye in a dark sky in the tail of the constellation of the Scorpion (Scorpius). M7 contains about 100 stars […]

Alnitak, Alnilam, Mintaka: The glorious belt of Orion

Alnitak, Alnilam, Mintaka: The glorious belt of Orion

[CLICK ON IMAGE FOR HIGH RESOLUTION /  Rogelio Bernal Andreo] Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie about 1,500 light-years away, born of Orion’s well-studied interstellar clouds. In fact, clouds of gas and dust adrift in this region have […]

Galaxies in space the size of the Milky Way head for a collision

Galaxies in space the size of the Milky Way head for a collision

[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble Legacy Archive, NASA, ESA; Processing: Judy Schmidt] What will survive this battle of the galaxies? Known as Seyfert’s Sextet, this intriguing group …. actually contains only four interacting galaxies. Near the center of this Hubble Space Telescope picture, the small face-on spiral galaxy lies in the distant background […]

Nanotechnology provides ‘life-style intelligence’ for forensic experts

Nanotechnology provides ‘life-style intelligence’ for forensic experts

Nanoparticles can reveal information held by fingerprints that is currently inaccessible. In particular, they can be engineered to bring antibodies that bind with metabolites contained in the sweat of the fingerprint. These metabolites are breakdown products of the consumption of cocaine or nicotine. When the antibodies recognize the metabolite, they cause a colour change. This […]

Hubble provides closeup of 100,000 stars in M15 near our galaxy’s center

[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble, NASA] Stars, like bees, swarm around the center of bright globular cluster M15. This ball of over 100,000 stars is a relic from the early years of our Galaxy, and continues to orbit the Milky Way’s center. M15, one of about 170 globular clusters remaining, is noted for […]

Solar spectrum shifted from absorption to emission during eclipse

Solar spectrum shifted from absorption to emission during eclipse

[CLICK ON IMAGE FOR HIGH RESOLUTION / Constantine Emmanouilidi] In a flash, the visible spectrum of the Sun changed from absorption to emission on November 3rd, during the brief total phase of a solar eclipse. [Normally a spectrum of the sun will show dark lines where where wavelengths of energy for elements have been absorbed […]
