    The German magazine Bild has a story that a team of astronomers have actually taken IR pictures of an exoplanet system around HR 8799, about 130 light years away. There are three planets, all larger than Jupiter, visible as three specks in the pictures. In addition, a team from the University of California has Hubble pictures in visible light of a triple Jupiter mass exoplanet orbiting Formalhaut, which is 25 ly away. Both discoveries are firsts for the exoplanet hunt.

    Here's a link to a story in Astronomy about this:

    and in Science Express:

    Actual pictures of an exoplanet! Bravo!

    Here's a short clip from Yahoo with Kalas explaining his discovery:

    It is quite an achievement. But I have seen many claims like hat. So let's see, who will confirm the results. As a scientist, you cannot be too careful with these announcements.

    BTW, isn't it convenient that HST/NASA brought up their press release exactly on the same day like the other group, although their result was around already for some time? Especially with this kind of news, it is astonishing. I am wondering, whether this was done on purpose in order to put the others in second line on the news. They also had to prove something after the recovery from the long blackout.

    The press release timing is certainly suspect, but not exactly surprising.

    As to confirmation, these four new exoplanets are already listed on exoplanet.eu which suggests to me that there's a fair confidence in the community that these are confirmable, if not actually independently confirmed. Now I'm coming at this from the outside, so whether that's meaningful at all I don't really know.

    Hard to imagine what a 3 mass J object orbiting a star could be other than a planet.
