... The Observatory Monitoring System (OMS) is part of the Hubble Space Telescope (HST) ground system at the Space Telescope Science Institute. OMS receives as inputs a file of commands for the HST and files of engineering telemetry data generated by the HST in response to those commands. This paper will discuss how, from its inputs, OMS software provides spacecraft jitter files during observations commanded in the input. ... The jitter image file will be archived for the user. ...

We present new results from high-resolution spectroscopic observations of the late-type fast rotator BD+22 4409, revealing interesting aspects about its magnetic activity that have not been considered before. Analysis of the extremely variable and rotationally broadened chromospheric H alpha emission profile provides clear evidence for an intense and continuous downflow of absorbing material. ... Unstable material would be expected to flow towards the poles along magnetic lines. ...

. NASA's Dawn spacecraft obtained this image of the giant asteroid Vesta with its framing camera July 9, 2011. It was taken from a distance of about 26,000 miles (41,000 kilometers) away from Vesta, which is also considered a protoplanet because it is a large body that almost became a planet.
