Mars Doesn’t Have as Many Minerals as Earth

Earth and Mars are very much alike, but also very different. Among other things, scientists find that Earth is much more mineral-rich than the Red Planet. It has 6,000 different minerals. By contrast, Mars has only 161. That’s a big difference. How could this have happened?

Did a Comet Airburst Destroy a Native American Community?

In 1908, when an object entered the Earth’s atmosphere above the Podkamennaya Tunguska River, it flattened 80 million trees over nearly 2,200 square kilometers, and sent atmospheric shock waves reverberating around the world. Fortunately, this event was in a remote region and very few people were believed to be killed.

Another New Way to Measure Distance in the Universe: Baryon Acoustic Oscillations

Measuring cosmic distances is a major challenge thanks to the fact that we live in a relativistic Universe. When astronomers observe distant objects, they are not just looking through space but also back in time. In addition, the cosmos has been expanding ever since it was born in the Big Bang, and that expansion is accelerating. Astronomers typically rely on one of two methods to measure cosmic distances (known as the Cosmic Distance Ladder). On the one hand, astronomers rely on redshift measurements of the Cosmic Microwave Background (CMB) to determine cosmological distances.

Virgin Galactic will launch some of its 1st space tourist customers on 'Galactic 03' flight Friday. But who's flying?

Virgin Galactic plans to launch its 'Galactic 03' space tourism mission on Sept. 8, sending three customers to the final frontier and back. You won't be able to watch it live, though.

A Last-Minute Addition to the Solar Orbiter Allows it to See More Deeply into the Sun’s Atmosphere

Spacecraft instruments are highly specialized and can take years to design, build, and test. But a last-minute hack to one of the instruments on the ESA’s Solar Orbiter has allowed the spacecraft to take some difficult observations it would otherwise have been unable to take.

Look to the east in the evenings throughout September to find the Great Square of Pegasus, a group of four stars of roughly equal brightness, as it climbs higher in the night sky.

The Most Distant Galactic Field Lines Ever Seen

The galaxies in our local Universe all have magnetic fields. Galactic magnetic fields can be generated by ionized gas within a galaxy, and these same magnetic fields affect the evolution of galaxies. But while modern galaxies have magnetic fields, did early ones? Astronomers are still trying to understand how galactic magnetic fields arise in young galaxies, but this can be a challenge without observational data. Now a team using data from the Atacama Large Millimeter/submillimeter Array (ALMA) has observed the magnetic field of a galaxy when the Universe was just 2.5 billion years old. The galaxy is known as 9io9. It takes 11 billion years for its light to reach us, making it the most distant galaxy for which we have observed a magnetic field.
