NASA’s faraway space snowman has flat, not round, behind

  • New Horizons is already 32 million miles (52 million kilometers) beyond Ultima Thule

CAPE CANAVERAL, Florida: The faraway space snowman visited by NASA last month has a surprisingly flat — not round — behind.
New photos from the New Horizons spacecraft offer a new perspective on the small cosmic body 4 billion miles (6.4 billion kilometers) away. The two-lobed object, nicknamed Ultima Thule, is actually flatter on the backside than originally thought, according to scientists.
Pictures released late last week — taken shortly after closest approach on New Year’s Day — provide an outline of the side not illuminated by the sun.
When viewed from the front, Ultima Thule still resembles a two-ball snowman. But from the side , the snowman looks squashed, sort of like a lemon and pie stuck together, end to end.
“Seeing more data has significantly changed our view,” Southwest Research Institute’s Alan Stern, the lead scientist, said in a statement. “It would be closer to reality to say Ultima Thule’s shape is flatter, like a pancake. But more importantly, the new images are creating scientific puzzles about how such an object could even be formed. We’ve never seen something like this orbiting the sun.”
Project scientist Hal Weaver of Johns Hopkins University, home to New Horizons flight control center, said the finding should spark new theories on how such primitive objects formed early in the solar system.
Ultima Thule — considered a contact binary — is the most distant world ever explored. New Horizons zipped past it at high speed, after becoming the first visitor to Pluto in 2015. Mission managers hope to target an even more distant celestial object in this so-called Kuiper Belt, on the frozen fringes of the solar system, if the spacecraft remains healthy.
New Horizons is already 32 million miles (52 million kilometers) beyond Ultima Thule. It will take another 1 ½ years to beam back all the flyby data.
The spacecraft rocketed from Florida in 2006.

Saudi Arabia in the crosshairs as cyber-raids target Gulf

  • Cyberattacks were ranked as the second most important risk after an “energy shock” in these three Gulf states, according to the WEF’s flagship Global Risks Report 2019
  • Criminal phishing attacks rising sharply, cybersecurity experts warn

RIYADH: Online phishing attacks are on the rise with experts warning of increasing numbers of cyber-raids targeting Saudi Arabia and other Gulf countries.
Phishing is a type of fraud where criminals target online victims, using deception to acquire users’ credentials, ranging from passwords to credit card and bank account details, and other financially sensitive information.
Cybersecurity experts say the numbers of attacks worldwide have risen dramatically, increasing from over 2 million in the first two weeks of February last year to more than 4.3 million in the same period this year.
Mohammed Khurram Khan, a professor of cybersecurity at King Saud University (KSU), told Arab News: “Saudi Arabia, due to its strong position in political, social and economic spheres, has been a key target for cyber-intrusions by state and nonstate actors aiming to compromise its national security.
“Various types of malware and scams, especially phishing, are used to target critical information infrastructure, which serve as the backbone of the economy,” he said.
More than 90 percent of malware is distributed by email with hackers seeking to trick users with fake invoices and other scams, said Khan, who is also the founder and CEO of the Global Foundation for Cyber Studies and Research, a Washington-based cybersecurity think tank.
“Computer users in Saudi Arabia have been confronted with more than 30 million phishing emails in recent years,” he said.
Khan said that awareness, training and “cyber-hygiene” were important to protect users and organizations from phishing scams.
KSU has developed a pioneering cybersecurity awareness product, “Rawam,” which helps organizations train employees to deal with malicious hacking, malware, ransomware, phishing and cyberattacks.
The bilingual tool has been used to train 100,000 staff in 40 different organizations, he said.
The World Economic Forum (WEF) last month warned of the growing likelihood of cyberattacks in the Gulf, with Saudi Arabia, the UAE and Qatar particularly vulnerable.
Cyberattacks were ranked as the second most important risk after an “energy shock” in these three Gulf states, according to the WEF’s flagship Global Risks Report 2019, released ahead of the annual forum in Davos.
Cybersecurity experts from the Kaspersky Lab, a multinational digital security provider, detected a sharp increase in phishing activities on the eve of the Valentine’s Day.
The overall number of user attempts to visit fraudulent websites detected and blocked by Kaspersky Lab in the first half of February exceeded 4.3 million.
“The spike offers a reminder that we should be cautious when surfing the web, even if we are just buying flowers for our loved one,” said Andrey Kostin, a senior web content analyst.
