Planet That Should Not Be,IS

In Astrophysics on June 17, 2013 at 08:27

Flights of Fancy, this is what I call about the Modern Astronomical Theories, and even Astrophysics.

Beyond Solar System Planet

Plant Outside Solar System

It has been believed that ,in Science, Scientists observe some phenomenon, find some more similar phenomenon, formulate a Theory, check with all available material and verify the Theory and announce it.

Not any more!

People find something which they do not understand yet, they publish it as an Axiom!

Be it drinking Coffee, Cancer,Black holes!

One such is the finding of a Planet that has been found by the Hubble telescope.

With the present Laws of Astrophysics and Physics, it should not be there.there, it should not Exist.

But IT IS!

Story:

TW Hydrae, a star located about 176 light years away, is one of the closest things in the universe we have to a time machine. That’s because it’s only about 8 million years old, and its believed to look a lot like what our own Solar System looked like in the first few million years of its existence. By studying TW Hydrae, astronomers can learn more about the history of our own Sun.

Recently, while observing this star, the Hubble Telescope found something pretty amazing – a gap in the star’s protoplanetary disk. The disk, which was discovered a few years ago, is an accretion of large amounts of material that are expected to coalesce into a planet over the course of time. The most likely reason why such a gap would exist would be theformation of the planet. As the planet traveled around the star, its gravity would either attract or push the disk material out of its way. Such a planet would be somewhere in between 6 to 28 times more massive than Earth.

If the gap really is where a planet is located, then that planet is 7.5 billion miles from its star. That’s about twice as far as Pluto’s distance from our own Sun, making this the planet that is furthest from its parent star that we know of.

Here’s the real kicker about this planet, though: if it’s there, then current astronomical theories about how planets form are at least partially wrong. Planets are expected to form slowly over time, accumulating more and more rock and dust as it travels through the protoplanetary disk. Because planets like this are so far out from their stars, their orbits are slower and there is less material available to form a planet. Given that, it should take about 200 million years for that planet to have formed – way more years than TW Hydrae has been around.

Camera Points At Billion Light Years Away Video

In Astrophysics, videos on November 21, 2012 at 21:33

A new Camera, equipped to look into Deep Space in an effort  to find out find more about Dark Energy.

This powerful Camera is in a high Plateau in Chile.

‘The most powerful sky-mapping instrument ever built is about to embark on a far-reaching survey of deepest space to find evidence of the theoretical force called Dark Energy. From a high plateau in Chile, the Dark Energy Camera is being pointed billions of light years into the cosmos in an effort by astronomers to answer questions about Dark Energy’s influence over the expansion of our universe. Elly Park reports.’

New 3-D Map of the Universe.

In Astrophysics on May 27, 2011 at 08:20

Astronomers have created the most complete 3-D map of our local universe, revealing new details about our place in the cosmos. The map shows all visible structures out to about 380 million light-years, which includes about 45,000 of our neighboring galaxies (the diameter of the Milky Way is about 100,000 light-years across).

The Triangulam Galxy.

 

The Triangulum Galaxy is located nearly 3 million light years from Earth. And, in a study that pushes the limits of observations currently possible from Earth, a team of NASA and European scientists recorded the “fingerprints” of mystery molecules in the Triangulum Galaxy, as well as the Andromeda Galaxy.

Figuring out exactly which molecules are leaving these clues, known as “diffuse interstellar bands” (DIBs), is a puzzle that initially seemed straightforward but has gone unsolved for nearly a hundred years. The answer is expected to help explain how stars, planets and life form.
