By looking at Earth's full natural history and evolution, astronomers may have found a template for vegetation fingerprints -- borrowing from epochs of changing flora -- to determine the age of habitable exoplanets.
NASA's Terra satellite provided a visible image of Super Typhoon Trami as it continued moving in a northwesterly direction in the Northwestern Pacific Ocean. Terra provided an amazing image of the large eye.
NASA's Terra satellite provided a visible image of Subtropical Storm Leslie as it was meandering around the North Central Atlantic Ocean on Sept. 24, 2018.
Brazilian researchers dated the families using a numerical simulation method to process current data to go back in time to the asteroid formation era.
Tropical Storm Kirk formed on Saturday, Sept. 22. By Monday, Sept. 24, Kirk lacked the closed circulation that is a prerequisite for tropical cyclone status. The NOAA-20 satellite provided a visible image of the storm at its peak.
Phobos, the larger of Mars' two tiny satellites, is the darkest moon in the solar system. This dark aspect inspired the hypothesis that the close-orbiting moon may be a captured asteroid, but its orbital dynamics seemed to disagree. A new study suggests Phobos' composition may be more like the volcanic crust of the Red Planet than it appears, consistent with an origin for the moon in an ancient, violent impact on Mars.
A new study shows that the breakdown of water molecules trapped in ancient Martian rocks likely produced enough chemical energy to sustain microorganisms for hundreds of millions of years beneath the Red Planet's surface.
NASA's Terra satellite provided an infrared look at Tropical Storm Trami, located just over 100 miles from Guam on Sept. 21, 2018. Infrared data provides temperature information that showed two areas of the highest, coldest cloud tops and most powerful storms within the tropical storm.
Researchers have developed innovative business models underlying the successful launch of space-related start-up technology companies in Costa Rica.
NASA's continued quest to explore our solar system and beyond received a boost of new information this week with three key missions proving not only that they are up and running, but that their science potential is exceptional.
