Many in the scientific community believe that it’s only a matter of time before a massive asteroid hits Earth. “A big rock will hit Earth eventually and we currently have no defence,” said billionaire <a href="https://www.businessinsider.in/elon-musk-says-we-have-no-defence-against-asteroid-god-of-chaos/articleshow/70748251.cms">Elon Musk</a>, commenting on the Apophis asteroid. <div type="javascript" title="Custom" contenttype="Video"><cdata><![CDATA[]]></cdata></div> While that may still be a possibility, NASA’s Jet Propulsion Laboratory (JPL) has at least narrowed down the possibility that the ‘big rock to hit Earth’ won’t be Apophis — not in 2029, 2036 or even 2068. “A 2068 impact is not in the realm of possibility anymore, and our calculations don’t show any impact risk for at least the next 100 years,” said Davide Farnocchai of NASA’s Centre for Near-Earth Object Studies (CNEOS). <div type="image" title="apophis_edited" msid="81719242" hostid="261" caption="&amp;lt;p&amp;gt;Apophis won&amp;#39;t be crashing into Earth for at least a century&amp;lt;/p&amp;gt;"></div> What would happen if Apophis crashed into Earth? It’s not uncommon for small asteroids between the size of five to ten metres to pose a threat as they make their close approach to Earth, but asteroids the size of Apophis — as big as three football fields — are rare. The potential impact would be the equivalent of 880 million tonnes of trinitrotoluene (TNT) exploding simultaneously. This would make it 65,000 times more destructive than the Hiroshima nuclear disaster. <div type="image" title="asteroid gif" msid="81719274" hostid="261" caption="&amp;lt;p&amp;gt;The animation depicts a mapping of the positions of known near-Earth objects (NEOs) at points in time over the past 20 years, and finishes with a map of all known asteroids as of January 2018&amp;lt;/p&amp;gt;"></div> Eliminating the doomsday prediction Apophis was determined to be <a href="https://www.businessinsider.in/science/space/news/apophis-the-god-of-chaos-asteroid-is-speeding-up-increasing-the-likelihood-of-it-hitting-earth-in-2068/articleshow/78895818.cms">under the influence of the Yarkovsky effect</a> in October 2020, by the University of Hawaii Institute for Astronomy. Simply put, it meant Apophis was getting pushed around by sunlight and speeding up in approach towards Earth. This made its orbit difficult to predict, increasing the likelihood of it crashing into Earth in 2068. In order to figure out whether the threat of a collision was real, JPL’s researchers decided to conduct a detailed analysis — using a new radar observation campaign coupled with a precise orbit analysis — of Apophis when the massive asteroid made a distant flyby of Earth on March 5. Tracking the asteroid with Deep Space Network’s 70-metre radio antenna and the 100-metre Green Bank Telescope, the scientists were able to capture Apophis on camera. <div type="image" title="Screenshot (695)_edited" msid="81719181" hostid="261" caption="&amp;lt;p&amp;gt;These images of asteroid Apophis were recorded by radio antennas at the Deep Space Network’s Goldstone complex in California and the Green Bank Telescope in West Virginia&amp;lt;/p&amp;gt;"></div> The images may appear pixelated, but considering that the asteroid was 17 million kilometres away — more than 44 times the distance between the Earth and the Moon — it’s an incredible accomplishment. “If we had binoculars as powerful as this radar, we would be able to sit in Los Angeles and read a dinner menu at a restaurant in New York.” said JPL scientist Marina Brozovic, who led the radar campaign. Using these images, not only did JPL rule out the possibility of Apophis hitting Earth in 2068 but it was also able to determine that the asteroid has a ‘bilobed’ or peanut-like appearance. According to NASA, this is a relatively common shape for big space rocks — larger than 200 metres in diameter — that fly by the planet. At least one in every six asteroids has two lobes.

According to the researchers at the University of Hawaiʻi Institute for Astronomy (<a href="https://www.hawaii.edu/news/2020/10/26/new-massive-asteroid-findings/">IfA</a>), it is under the influence of the Yarkovsky effect. <div type="image" title="apophis discovery" msid="78896065" hostid="261" caption="&amp;lt;p&amp;gt;Image of Asteroid Apophis when it was first discovered on 14 June 2004&amp;lt;/p&amp;gt;"></div> This is when the asteroid speeds up because its thermal radiation is no longer uniform. Simply put, some parts of the asteroid are heating up faster than other parts. Before the detection of this effect, Apophis — which is the size of three football fields — was likely to fly past Earth in 2068. However, the impact of the Yarkovsky acceleration means that the there is still a possibility that the massive asteroid may crash into the planet when it rolls around in another 50 years. The potential impact would be the equivalent of 880 million tons of trinitrotoluene (TNT) exploding simultaneously. This would make it 65,000 times more destructive than the Hiroshima nuclear disaster. What is the Yarkovsky effect? The Yarkovsky effect makes it difficult to make long term predictions about how an asteroid will move over long periods. <div type="image" title="YarkovskyEffect_NRAO_300dpi_large" msid="78896106" hostid="261" caption="&amp;lt;p&amp;gt;Diagram explaining the Yarkovsky effect&amp;lt;/p&amp;gt;"></div> It happens where sunlight heats up the dayside of the asteroid, and after the asteroid turns, the night side releases the heat. That release can exert a small thrust, which can result in a change of direction. It can also accelerate or decelerate the asteroids current speed. The National Aeronautics and Space Administration’s (NASA) most recent endeavour to collect a sample from Asteroid Bennu is one of the ongoing initiatives to understand the influence of the Yarkovsky effect. The Apophis asteroid could hit Earth "The new observations we obtained with the Subaru telescope earlier this year were good enough to reveal the Yarkovsky acceleration of Apophis, and they show that the asteroid is drifting away from a purely gravitational orbit by about 170 meters per year, which is enough to keep the 2068 impact scenario in play," said <a href="https://www.hawaii.edu/news/2020/10/26/new-massive-asteroid-findings/">Dave Tholen</a>, co-author of the paper presented at the 2020 virtual meeting of the Division for Planetary Sciences of the American Astronomical Society. It’s not uncommon for small asteroids between the size of 5 to 10 meters to pass by Earth, but asteroids the size of Apophis are rare. Not only are they fewer in number, but don’t normally come this close to Earth. Before 2068 rolls around, Apophis is scheduled to visit Earth even sooner on April 13, 2029. The massive 340-meter asteroid will be visible streaking across Earth’s skies without the aid of a telescope or binoculars. <div type="image" title="apophis" msid="78895938" hostid="261" caption="&amp;lt;p&amp;gt;NASA animation shows the distance between the Apophis asteroid and Earth at the time of the asteroid&amp;#39;s closest approach. The blue dots are the many man-made satellites that orbit our planet, and the pink represents the International Space Station.&amp;lt;br&amp;gt;&amp;lt;/p&amp;gt;"></div> According to NASA, even this close encounter <a href="https://www.businessinsider.in/elon-musk-says-we-have-no-defence-against-asteroid-god-of-chaos/articleshow/70748251.cms">may have an impact on Apophis</a>. Since it will only be 30,000 kilometers from the planet — Earth’s gravitational field may impact the way the asteroid spins or result in a change on its surface. <a href="https://www.businessinsider.in/science/space/news/ufologist-claims-the-god-of-chaos-asteroid-will-strike-somewhere-over-europe/articleshow/71537022.cms">Ufologist Michael Horn</a> claims if Apophis were, in fact, to crash into Earth, the impact point would be somewhere over Europe.

"We will celebrate Holi with the Delhi and UP Police personnel deployed at the border. We will make the necessary arrangements for them and communicate to them asking them to celebrate Holi together," Tikait told. He said, "Whenever there are festivals celebrated at the India-Pakistan border, there are pleasantries exchanged at the border, so why can't it be done here at the Ghazipur border? If pleasantries are not exchanged, then it will mean that Ghazipur border is more dangerous than Pakistan border. "If all the security forces and police officials do not exchange Holi pleasantries with them, then we (farmers) will think that the Central government does not want to talk to us. The Delhi Police will be given an invitation to join us for Holi celebrations as they, too, are on police duty away from their homes. Everyone should be present at the border in the evening on the occasion of 'Holika Dahan'." Asked will you also invite the government on Holi celebrations? To this, Rakesh Tikait said, "We (farmers) will only invite the security forces and policemen at the border and not the Central government. At the Ghazipur border, the farmers have been singing songs and beating drums to celebrate the Holi, and would be burning the copies of three Union farm laws on the occasion of 'Holika Dahan'.

After the switch to remote work, brute-force attacks against RDP -- which is perhaps the most popular remote desktop protocol and is used to access Windows or servers -- skyrocketed, reaching a new high of 409 million worldwide in November 2020, showed the research from cybersecurity firm Kaspersky. In a brute-force attack, attackers test different usernames and passwords until the correct combination is found -- and they gain access to the corporate resources. When the world went into lockdown in March 2020, the total number of brute-force attacks against RDP jumped from 93.1 million worldwide in February 2020 to 277.4 million 2020 in March -- a 197 per cent increase, according to Kaspersky's telemetry. The numbers in India went from 1.3 million in February 2020 to 3.3 million in March 2020. From April 2020 onward, monthly attacks never dipped below 300 million, and they reached a new high of 409 million attacks worldwide in November 2020. The highest number of attacks, 4.5 million in India, was recorded in July 2020, showed the data. In February 2021 -- nearly one year from the start of the pandemic -- there were 377.5 million brute-force attacks -- a far cry from the 93.1 million witnessed at the beginning of 2020. India alone witnessed 9.04 million attacks in February 2021. The total number of attacks in India from February-December 2020 was around 37 million, while the total number of attacks recorded in India during January and February 2021 are around 15 million. "Remote work isn't going anywhere. Even as companies begin considering re-opening their workplaces, many have stated that they will continue to include remote work in their operating model or pursue a hybrid format," Dmitry Galov, <keyword id="1266061" type="PERSON" weightage="20" keywordseo="security-expert">security expert</keyword> at Kaspersky, said in a statement. "That means it's likely these types of attacks against remote desktop protocols will continue to occur at a rather high rate. 2020 made it clear that companies need to update their security infrastructure, and a good place to start is providing stronger protection for their RDP access." Enabling access to RDP through a corporate VPN and enabling use of Network Level Authentication (NLA) when connecting remotely are among the recommendations that experts offered to keep organisations safe from brute-force attacks.
