Source link The near-Earth object (NEO) impact hazard has been the topics of various reports and studies in recent years. The news of the potential devastation from NEOs have now been captured in a new study from ScienceDaily.
The report reveals that current technology can’t track many dangerous NEOs, leaving us blind to the potential risks they pose. Astronomers have significant challenges in tracking, as current NEOs appear too faint to be detected until they are dangerously close to Earth.
NEOs are asteroids and comets orbiting the Sun whose orbits occasionally take them into Earth’s vicinity. In the past, NEOs have collided with the Earth and there remains a risk of future events. Scientists have estimated that most NEOs aren’t discovered until they pass within detection range.
One of the ways to detect NEOs is by using ground-based telescopes, which scans the sky for objects that are moving relative to stars. However, these traditional searches have difficulty discovering NEOs for a variety of reasons, including their dimness, the moon’s brightness, and the nearly constant speed at which asteroids move.
The report recommends new technology and methods, such as upgraded tracking systems with more sensitive detectors and larger databases of NEOs. Additionally, the report advocates for further international collaborations to push these advancements further.
The authors of the report state that these improvements can help in better identifying and reducing the risk of NEOs. Ultimately, the new technology and methods will help scientists to better understand our solar system and help to identify threatening NEOs more quickly.
In conclusion, ScienceDaily’s new report provides insight on the challenges in tracking NEOs and offers potential solutions. With the proposed methods and technology, scientists can help to safeguard our planet and provide more clarity on the mysterious NEOs.
