3) Planets and Brown Dwarfs . ... By its nature, this method is most sensitive to massive planets orbiting close to their stars. ... That means that some of the more massive extrasolar planets could actually be brown dwarfs (although the statistics of the finds suggest that most of them are not). ... Another possible difference between brown dwarfs and massive planets is how they are born. ... They would base the fundamental definition on the mode of formation: a planet is built from planetesimals. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... Centaurus A : 15,000,000 light years away, in the constellation Centaurus, the closest AG to Earth . ... Astronomers think that the reason for the unusual shape of this galaxy is because hundreds of millions of years ago two galaxies, one dusty spiral and one bright ellipictal, collided causing a massive black hole in the middle and bright emmision of light. ... Andromeda galaxy: 2.8 million light years away, closest spiral galaxy to earth, farthest object one can see without a telescope. ...

... Planets . ... Stars . Exoplanets . ... Most exoplanets so far discovered fall into the category of тАШhot JupitersтАЩ, these are giant planets orbiting very close to their parent star. ... Note that we have discovered so many hot Jupiters because they are the easiest type of planet to find, they are not necessarily particularly common in the galaxy. ... Subsequently several similar hot and€а fuzzy worlds have been discovered the same way, proving this that this planet is not a one-off oddball. ...

. Next: Triple with velocity curves Up: Fit scenarios Previous: Single-lined spectroscopic binary with Contents . Select all three masses as fit parameters. The mass ratio of the close pair will be constrained, but as far as the absolute masses, this system is identical to a single-lined binary. Christian Hummel 2015-04-28

Astronomers have discovered a massive cluster of young galaxies forming in the distant universe. The growing galactic metropolis, named COSMOS-AzTEC3, is the most distant known massive "proto-cluster" of galaxies, lying about 12.6 billion light-years from Earth. ... The other dots in this picture are stars or galaxies that are not members of the cluster тАФ most of them are located closer to us than the cluster, but some are farther away. The two brightest spots are stars. ...

A search for new magnetic stars, new CP stars, measurements of magnetic fields in stars . ...

The most massive black holes in the nearby Universe seem to largely be hosted by massive central cluster galaxies. The ultra-massive black hole in NGC 1277, reported by van den Bosch et al. based on a stellar kinematic measurement, is an extreme outlier in this respect. NGC 1277 is not a central cluster galaxy, but a lenticular galaxy in the Perseus Cluster, at a distance of about 3.8 from the central cluster galaxy. ...

... Following several successful moon landings,NASA decided to use its last Saturn V not to fly to the moon but to place in low Earth orbit a large space station, named Skylab. ... It was followed that year by three manned flights using the smaller Saturn IB, each carrying 3 astronauts for a prolonged stay aboard Skylab. ...
