NASA’s Webb space telescope to peer deep into our solar system’s outermost graveyard of planet formation; a bizarre, frozen zone of freakish objects on strange solar orbits.

This week, NASA’s OSIRIS-Rex spacecraft successfully touched and collected a sample from the surface of asteroid Bennu—without a human at the controls…
NASA scientists identified a molecule in Titan’s atmosphere that has never been detected in any other atmosphere. In fact, many chemists have probably barely heard of it or know how to pronounce it: cyclopropenylidene, or C3H2. Scientists say that this simple carbon-based molecule may be a precursor to more complex compounds that could form or feed possible life on Titan.
Asteroid Apophis is gaining speed as it travels on its path towards Earth. The object is releasing radiation, which acts like a tiny thruster — and experts warn it could make impact 48 years from now.
Forget water on the moon, NASA has now struck gold.
NASA’s Hubble Space Telescope has discovered a rare, heavy and immensely valuable asteroid called “16 Psyche” in the Solar System’s main asteroid belt between Mars and Jupiter.
Asteroid Psyche is located at roughly 230 million miles (370 million kilometers) from Earth and measures 14 miles (226 kilometers) across, about the size of West Virginia. What makes it special is that, unlike most asteroids that are either rocky or icy, Psyche is made almost entirely of metals, just like the core of Earth, according to a study published in the Planetary Science Journal on Monday.
This effect, known as gravitational redshift, is critical for maintaining GPS on Earth.
Gravitational redshift, an effect predicted by Albert Einstein that is crucial for maintaining the Global Positioning System (GPS) on Earth, has been observed in a star system in our galaxy.
NASA is prepping its Dragonfly mission to go look for signs of life on the enticing moon.
Europe will provide a habitat module and a refueling module for the Gateway outpost.
Europe signed a memorandum of understanding on Tuesday (Oct. 27) formalizing its collaboration on Gateway, NASA’s planned outpost in lunar orbit.
The meteorite crashed on earth on 2018. But it seems the news just came out. The good news is that it crashed on a frozen lake.
A fireball that fell to Earth in 2018 contains “pristine extraterrestrial organic compounds” that could help tell us how life formed, scientists say.
The meteor arrived on Earth in January 2018, as a streaking fireball visible across the sky of the US Midwest. Scientists were able to track it using weather radar, and hunters picked the meteorite up from the ground before its chemical makeup was changed by exposure to liquid water.
Now, Casey Honniball at NASA’s ASA Goddard Space Flight Center in Maryland, US, and colleagues have detected a chemical signature that is unambiguously H2O, by measuring the wavelengths of sunlight reflecting off the moon’s surface. The data was gathered by the Stratospheric Observatory for Infrared Astronomy (Sofia), a modified Boeing 747 carrying a 2.7-metre reflecting telescope.
The water was discovered at high latitudes towards the moon’s south pole in abundances of about 100 to 400 parts per million H2O. “That is quite a lot,” said Mahesh Anand, professor of planetary science and exploration at the Open University in Milton Keynes. “It is about as much as is dissolved in the lava flowing out of the Earth’s mid-ocean ridges, which could be harvested to make liquid water under the right temperature and pressure conditions.”
The existence of water has implications for future lunar missions, because it could be treated and used for drinking; separated into hydrogen and oxygen for use as a rocket propellant; and the oxygen could be used for breathing. “Water is a very expensive commodity in space,” said Anand.
