Planets! Planets! It’s Full of Planets!

The portion of the sky the Hubble Space Telescope is currently looking at is full of planets both big and small

Astronomy News – One of the greatest things about being an astronomer is the excitement of mystery and wonder you feel every time you discover something you never even suspected. This must have been the feeling running through the minds of astronomers looking at the data provided by the Hubble Space Telescope indicating the presence of planets around distant stars. The rush of adrenalin as they went over the data they had worked and waited for must have been truly euphoric.

What kind of planets would they find? Smaller rocky worlds like Earth, larger gas planets like Jupiter, or some unusual planet never before dreamed of. All of their hard work and dedication to the task-at-hand is about to open a door of discovery to worlds of wonder. Worlds with environments unlike anything we have experienced on Earth, where life we could never envision might have evolved. This is why astronomers spend countless days, weeks, months and ultimately lives studying the sky above our heads.

Astronomers see a sky full of planets

The small portion of the sky being studied by astronomers using the Hubble Space Telescope is full of planets. Some appear to be of a similar rocky composition to our home planet while others appear to be totally inhospitable to Earth-type life. Planets like Earth are thought to be mainly composed of rocky material, which is denser and thus heavier than the materials making up gas planets. The planets being found orbiting stars in the portion of the sky being surveyed by Hubble are helping to rewrite planet formation theory and other areas of astronomical study. Astronomers are finding planets of types they were expecting to find, and a few they weren’t expecting to see.

The first planets found by the Hubble Space Telescope were large gas giants, like Jupiter and Saturn, but more recent finds have included planets similar in size and possible composition to Earth. Astronomers want to study Earth-like planets in an effort to uncover more secrets concerning the birth of our own solar system and the planet, which could give us clues to the development and evolution of Earth-like life in our universe. More recent developments even include the first direct imaging of a planet orbiting a distant star.

The truly amazing part is Hubble is only surveying a portion of the sky with around 100,000 suns and we’re finding more and more planets as astronomers continue to refine their planet finding techniques and instruments. Once we extrapolate and calculate the number of possible planets, using the available data so far gathered, we find the number of possible planets to be beyond count.

Astronomers will use the James Webb Space Telescope to journey to the beginning of space and time

During the 2013 human space odyssey, astronomers explored a portion of the night sky with the Hubble Space Telescope and exclaimed. It’s full of planets! In the years ahead during the human journey to the beginning of space and time, we expect astronomers to discover undreamed-of worlds, revolving around suns we humans can’t even conceive of. Especially once the James Webb Space Telescope comes online we should expect to visit undreamed of planets.

Best to buckle your seatbelt and prepare for the ride of your life! The human journey to the beginning of space and time is about to take off to planets beyond imagination. In the months and years ahead we expect to visit worlds with environments we would find inhospitable at best. Worlds where human survival would be doubtful and any life we found would be unusual beyond imagination.
