Habitable worlds may be far more common than thought, Israeli study says

Published in the peer-reviewed The Astrophysical Journal, the research focuses on tidally locked planets, worlds that always show the same face to their star.

 Life beyond Earth may exist in far stranger places than scientists once thought, a new study suggests. January, 22.

Milky Way may not be the shape we thought - study

Over the years, astronomers have classified galaxies into three main shapes: elliptical, irregular and spiral.

 This illustration shows a stage in the predicted merger between our Milky Way galaxy and the neighboring Andromeda galaxy, as it will unfold over the next several billion years. In this image, representing Earth's night sky in 3.75 billion years, Andromeda (left) fills the field of view

Scientists discover that galactic collisions cause quasars - study

Contrary to previous beliefs that the quasars are formed at the peak of galactic collision, researchers found that they are actually formed during the initial stages of collision.
