Venus Express goes gently into the night
ESA's Venus Express has ended its eight-year mission after far exceeding its planned life. The spacecraft exhausted its propellant during a series of thruster burns to raise its orbit following the low-altitude ...
Tropical trees may not be the carbon sink planet scientists have been hoping for
What is the average surface temperature of the planets in our solar system?
It's is no secret that Earth is the only inhabited planet in our Solar System. All the planets besides Earth lack a breathable atmosphere for terrestrial beings, but also, many of them are too hot or too ...
Increase in CO2 has not stimulated growth of tropical trees
Since the start of the industrial revolution in 1850, atmospheric CO2 levels have increased by about 40%. However, contrary to expectations, the growth of tropical trees has not increased as a result. Th ...
MAVEN mission identifies links in chain leading to atmospheric loss
Early discoveries by NASA's newest Mars orbiter are starting to reveal key features about the loss of the planet's atmosphere to space over time.
November global temps dip, Earth still nears heat record
The Earth is still on track for a record-breaking year for heat even though the average global temperature last month dipped to the seventh warmest since 1880, US government scientists said Monday.
