Credit: ESA/Hubble & NASA This image from the NASA Hubble Space Telescope shows planetary nebula Hen 3-1333. Planetary nebulae have nothing to do with planets - they actually represent the death throes of mid-sized stars like the sun. As they puff out their outer layers, large, irregular glob...
The Magnetosphere-Ionosphere Coupling (MICA) rocket, to be launched from the Poker Flat Research Range, will use a Terrier-Black Brant Mark 1 sounding rocket to deliver a scientific payload to an altitude of ~400 km in the neighbourhood of an auroral arc. Through this mission, we hope to learn mor...
Title: B2 0954+25A: a typical Fermi blazar or a gamma-loud Narrow Line Seyfert 1 Authors: G. Calderone, G. Ghisellini, M. Colpi, M. Dotti B2 0954+25A, detected by the Fermi satellite, is a blazar with interesting observational properties: it has been observed to transit from a jet dominated to a di...
Title: On the nature of the galactic early-B hypergiants Authors: J. S. Clark, F. Najarro, I. Negueruela, B. W. Ritchie, M. A. Urbaneja, I. D.

The first animals sent into space were fruit flies aboard a U.S.-launched V2 rocket on February 20, 1947. The purpose of the experiment was to explore the effects of radiation exposure at high altitudes. The rocket reached 109 km in 3 minutes and 10 seconds, past both the U.S. 50-mile and the internat...
