Sun may delay plans for sending humans to Mars

Less solar activity indicates a weaker magnetic field on the sun. A weak field lets cosmic rays into the solar system, posing a radiation hazard for astronauts.

How often might Hawaii get a monster tsunami?

Scientists say that the tsunami that hit Japan in 2011 was a thousand-year event. A monster wave might strike Hawaii about as often.

First-ever image of 5th order rainbow!

The fabled quinary or 5th order rainbow is made by sunlight reflected five times inside raindrops. Now, for the first time, we have an image of one.

Video: Comet Siding Spring’s close encounter with Mars

Here’s a 2-minute video on the comet’s October 19 near-miss of Mars, and how orbiting spacecraft will evade onslaught of dust particles from the comet.

Milky Way strips nearby galaxies of star-forming hydrogen

Astronomers have discovered that our nearest galactic neighbors are devoid of star-forming gas, and that our Milky Way is to blame.

What are super-Earths made of?

Astronomers struggle to learn about super-Earths – bigger than our Earth, smaller than Neptune – the most common type of planet found by the Kepler spacecraft.

The 'north pole' -- that is, the direction of magnetic north -- was reversed a million years ago. This map shows how, starting about 789,000 years ago, the north pole wandered around Antarctica for several thousand years before flipping 786,000 years ago to the orientation we know today, with the pole somewhere in the Arctic.

Earth’s last magnetic reversal took less than 100 years

A study demonstrates that Earth’s last magnetic reversal – 786,000 years ago – happened in roughly the span of a human lifetime.

Spacecraft catches Mars atmosphere in act of escaping

Earth’s atmosphere is leaking into space, too, but only very, very slowly. Meanwhile, Mars is thought to have lost much of its atmosphere already.

Crocodiles work as a team to hunt their prey

Crocs are able to conduct highly organized game drives. They might be second only to humans in their hunting prowess, says a researcher.

Massive icebergs once drifted to Florida

New research suggests that during Earth’s last ice age – about 21,000 years ago – icebergs regularly reached South Carolina and even southern Florida.

Australian astronomers say our Milky Way galaxy has only half the dark matter we thought it did. If so, it explains the shortage of Milky Way satellites.

Active moon volcanos in geologically recent times

Last volcanic activity on moon thought to be a billion years ago. Now small lava flows on moon’s dark plains suggest activity as recently as 50 million years ago.
