NASA-funded simulations show how massive collisions delivered metal to early Earth
Washington, Dec 6 (IBNS): Planetary collisions are at the core of our solar system’s formation. Scientists have long believed that after the Moon’s formation, the early Earth experienced a long period of bombardment that diminished about 3.8 billion years ago.
The changing colors of our living planet

New study sheds light on how earliest forms of life evolved on Earth
Sydney, Nov 12 (IBNS): A new study led by ANU has shed light on how the earliest forms of life evolved on Earth about four billion years ago.
NASA pinpoints cause of Earth’s recent record carbon dioxide spike
Washington, Oct 13 (IBNS): A new NASA study provides space-based evidence that Earth’s tropical regions were the cause of the largest annual increases in atmospheric carbon dioxide concentration seen in at least 2,000 years.
Asteroid to fly safely past Earth today, says NASA
Washington, Apr 19 (IBNS): A relatively large near-Earth asteroid discovered nearly three years ago will fly safely past Earth on Apr 19 at a distance of about 1.1 million miles (1.8 million kilometers), or about 4.6 times the distance from Earth to the moon, said astronomers.
Comet that took a century to confirm passes by Earth
Washington, Apr 1 (IBNS): On Apr 1, 2017, comet 41P will pass closer than it normally does to Earth, giving observers with binoculars or a telescope a special viewing opportunity.
Google hails NASA's exoplanets discovery, doodles
Mountain View, Feb 23 (IBNS): Tech giant Google on Thursday dedicated a doodle to celebrate NASA's latest discovery, where the agency found out about seven Earth-like exoplanets.
Comet’s trip past Earth offers first in a trio of opportunities
Washington, Feb 11 (IBNS): Comet hunters still have a chance to see comet 45P/Honda-Mrkos-Pajdušáková in the next few days using binoculars or a telescope. It’s the first of a trio of comets that will -- between now and the end of 2018 -- pass close enough to Earth for backyard observers to try to spot and for scientists to study using ground-based instruments.
NOAA’s GOES-16 Satellite sends first images to Earth
Washington, Jan 24 (IBNS): GOES-16, the first spacecraft in NOAA’s next-generation of geostationary satellites, has sent the first high-resolution images from its Advanced Baseline Imager (ABI) instrument. Included among them are a composite color full-disk visible image of the Western Hemisphere captured on January 15, 2017. Created using several of the ABI’s 16 spectral channels, the full-disk image offers an example the satellite’s advanced technology.
Revolutions in understanding the Ionosphere, Earth’s interface to space
Washington , Dec 15 (IBNS): Scientists from NASA and three universities have presented new discoveries about the way heat and energy move and manifest in the ionosphere, a region of Earth’s atmosphere that reacts to changes from both space above and Earth below.
NASA small satellites set to take a fresh look at Earth
New York, Nov 8 (IBNS): Beginning this month, NASA is launching a suite of six next-generation, Earth-observing small satellite missions to demonstrate innovative new approaches for studying our changing planet.
Earth's Moon hit by surprising number of Meteoroids: NASA
Washington, Oct 14 (IBNS): The moon experiences a heavier bombardment by small meteoroids than models had predicted, according to new observations from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft.
