Neptune's elliptical, oval-shaped orbit keeps the planet ... of a general class of planets that appear common across the galaxy. Studies looking at the variety of exoplanets discovered in recent ...

This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years ...

These two exoplanets, a super-Earth and a sub-Neptune, are common in the galaxy, yet are absent from our system. This discovery paves the way for future ...

However, not all spiral galaxies are created equal, as two recent images from the Hubble Space Telescope show. The image above shows galaxy NGC 3596, a neat and orderly spiral galaxy. And the image ...

Neptune’s orbit is essentially circular and in the same plane as most planets (the ecliptic plane), while Pluto’s orbit is elliptical and tilts 17º to the ecliptic. So, if Pluto and Neptune ...

“At the very least, we are convinced that its strength has been underestimated.” The huge elliptical galaxy ESO 325-G004 shone 10,000 times brighter when it formed than it does today. These types of ...

as opposed to the other two main categories of galaxy shapes — elliptical and irregular. The Milky Way – the galaxy that includes Earth and our solar system – is an example of a spiral galaxy.

Then, the solar system will have a new cosmic address: A giant elliptical galaxy, formed by the collision and merger of the Milky Way and Andromeda. This isn’t a chapter ripped from science ...

My collaborators and I have just tackled one of astrophysics’ enduring mysteries: how massive elliptical galaxies can form. Now, for the first time, we have solid observational evidence that ...
