'Magnetic' Discovery May Reveal Why Earth Supports Life and Mars Doesn't
Earth's magnetic field, which protects the planet from harmful blasts of solar radiation, is much older than scientists had previously thought. This invisible, protective shield likely existed shortly after the planet formed; a finding that could shed light on why Earth is habitable and Mars is not. Earth's magnetic field helped make life on the planet possible. Without our magnetic field, solar winds would strip away the planet's atmosphere and oceans.

an artist's impression of a black hole in the center of a blue disk
Some supermassive black holes at the centre of galaxies are devouring the surrounding material. They also divert part of it away through powerful winds and jets. Astronomers studying the supermassive black hole at the centre of the galaxy IRAS F11119+3257 have found proof that the winds blown by the black hole are sweeping away the host galaxy’s reservoir of raw material to form stars.

This false colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER's primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up Mercury's surface.

Beatrice Tinsley - Wikipedia
"Beatrice Muriel Hill Tinsley (27 Jan 1941 – 23 Mar 1981) New Zealand astronomer and cosmologist whose research made fundamental contributions to the astronomical understanding of how galaxies evolve with time. Tinsley completed pioneering theoretical studies of how populations of stars age and affect observable qualities of galaxies. Collaborated on research into models investigating whether universe is closed or open."
