Goldstone Radar Observations of Asteroid 2001 FO32
On March 21, 2021, the large asteroid 2001 FO32 made a close approach with our planet, passing at a distance of about 1.25 million miles (2 million kilometers) — or 5 1/4 times the distance from Earth to the Moon. While there was no risk of the near-Earth asteroid colliding with Earth as its orbit is very well known, scientists at NASA's Jet Propulsion Laboratory in Southern California took the opportunity to capture these radar images of the asteroid as it tumbled past.
Other radar observations were carried out by scientists using the 34-meter DSS-43 antenna at the Deep Space Network's Canberra Deep Space Communication Complex in Australia. Along with the Commonwealth Scientific and Industrial Research Organisation's Australia Telescope Compact Array near Narrabri in New South Wales, both antennas worked together to track 2001 FO32.
Asteroid equal to the size of football field to fly past Earth on May 4, but here's the good
NASA has detected another asteroid heading towards the Earth at a much faster pace than the previous ones. This comes after the God of Destruction Apophis, and the biggest asteroid of the year 2021, has passed through the Earth. Scientists have said that this asteroid will pass safely from a distance of about 3.4 million kilometers from the Earth.
The new asteroid called AF8 is the size of a football field and that is why NASA scientists are keeping a close eye on it as it could dangerous, as per the US Space Agency. According to scientists, this asteroid will pass near the Earth on May 4.
The Psyche Mission: Visiting a metal asteroid | Space
Psyche is a NASA mission expected to launch in 2022 that will explore a 140-mile-wide (225 kilometers) metallic asteroid called 16 Psyche. No spacecraft has ever visited an object like 16 Psyche, which is thought to be the exposed core of a demolished planet. The mission is expected to provide important insights into planetary formation.
Along with a mission called Lucy that will visit primordial asteroids near Jupiter, Psyche was approved in January 2017 as part of NASA's Discovery program. "This is what Discovery Program missions are all about — boldly going to places we've never been to enable groundbreaking science," Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate in Washington, D.C., said in a statement at the time.
Yet Another Asteroid to Zoom Past Earth, This Time the Celestial Body is Size of a Football Field
After the God of Destruction Apophis aka the largest asteroid of 2021, another Asteroid has been detected heading towards the Earth. Although it is coming at a much faster pace than the earlier ones, it will pass safely from a distance of about 3.4 million kilometers from the Earth, according to NASA.
The NASA scientists have confirmed that the new asteroid, named AF8 is the size of a football field. Its size is estimated to be between 260 to 580 meters. Reportedly, the size of AF8 is way smaller than massive asteroids which have passed by the Earth, but it is potent to cause harm and is deemed dangerous by the scientist.
Artificial Neural Network classification of asteroids in the M1:2 mean-motion resonance with Mars
V Carruba, S Aljbaae, R C Domingos, W Barletta, Artificial Neural Network classification of asteroids in the M1:2 mean-motion resonance with Mars, Monthly Notices of the Royal Astronomical Society , 2021;, stab914, https://doi.org/10.1093/mnras/stab914
Artificial neural networks ( ANN ) have been successfully used in the last years to identify patterns in astronomical images. The use of ANN in the field of asteroid dynamics has been, however, so far somewhat limited. In this work we used for the first time ANN for the purpose of automatically identifying the behaviour of asteroid orbits affected by the M1:2 mean-motion resonance with Mars.
Asteroid that wiped out dinosaurs probably helped produce rainforests
It was bad news for dinosaurs. But in the tropical rainforest, their loss was flowers' gain, a new study in the journal Science suggests.
To figure out what the area was like before the fiery extinction event, the researchers studied leaf and pollen fossils from the region. They tell a story of two different forests. Although the region was wet and warm before the crash, it teemed with conifers and ferns, and the widely spaced trees let in large patches of light.
