Landscapes give latitude to 2-D material designers

Researchers predict and experimentally confirm that two-dimensional materials grown onto a cone allows control over where defects appear. These defects, called grain boundaries, can be used to enhance the materials' electronic, mechanical, catalytic and optical properties.

Lunar dynamo's lifetime extended by at least 1 billion years

more »
Astronomers report that a lunar rock collected by NASA's Apollo 15 mission exhibits signs that it formed 1 to 2.5 billion years ago in the presence of a relatively weak magnetic field of about 5 microtesla. That's around 10 times weaker than Earth's current magnetic field but still 1,000 times larger than fields in interplanetary space today.

Successful filming of fastest aurora flickering

more »
Researchers conducted a 3 year continuous high-speed imaging observation at Poker Flat Research Range, Alaska, USA, and identified the physics behind the flickering of aurora. At the same time, they discovered faster flickerings at speeds of 1/60-1/50 and 1/80 of a second.

The mystery of the pulsating blue stars

more »
In the middle of the Chilean Atacama desert, a team of astronomers are monitoring millions of celestial bodies. In 2013, the team was surprised when they discovered, in the course of their survey, stars that pulsated much faster than expected. In the following years, the team studied these stars in more detail and concluded that they had stumbled upon a new class of variable star.

August's Lunar Eclipse

more »
August's Full Moon is framed in this sharp, high dynamic range composition. Captured before sunrise on August 8 from Sydney, Australia, south is up and the Earth's dark, umbral shadow is at the left, near the maximum phase of a partial lunar eclipse. Kicking off the eclipse season, this time the Full Moon's grazing slide through Earth's shadow was visible from the eastern hemisphere. Up next is the much anticipated total solar eclipse of August 21. Then, the New Moon's shadow track will include North America, the narrow path of totality running coast to coast through the United States.
