Here’s a timelapse of images over 2.5 hr from May from @keckobservatory of the supermassive black hole Sgr A*. The black hole is always variable, but this was the brightest we’ve seen in the infrared so far. It was probably even brighter before we started observing that night! pic.twitter.com/MwXioZ7twV— Tuan Do (@quantumpenguin) August 11, 2019 Scientists aren’t quite sure why this strange flash occurred, but it’s apparently nothing to be concerned about. Speaking to ScienceAlert, Tuan Do (an author on the study which spotted the bright light) said the flash could be the result of another star (S02) passing close by, thereby changing the way gas flows into the black hole. Another working theory is the flash was caused by G2, a gas cloud which also recently passed close (36 light-hours) to the black hole in 2014. There is a possibility this is a delayed reaction to that event. 3 Other teams and telescopes, such as Spitzer, Swift, Chandra, and ALMA, have also been observing Sagittarius A*. Do is curious to see if they too spotted the strange emission. Perhaps that data can help shed new light on this strange burst of infra-red light. Taken when I was @keckobservatory, this raw image shows the brightest Sgr A* has ever been observed in the infrared (center). The emission associated with the black hole also changed by a factor of 75 over that night. Is Sgr A* waking up? Will we finally see 🎆? pic.twitter.com/lX7ZO2PhX2— Tuan Do (@quantumpenguin) August 8, 2019 16 Photos What is a black hole? The universe’s dark, mysterious monsters Tags Sci-Tech Culture Robin Dienel/Carnegie Institution for Science In news that reads like the beginning of a dire science fiction novel Sagittarius A*, the supermassive black hole at the centre of our galaxy, has emitted a large burst of infrared radiation brighter than anything ever produced by that black hole. The black hole is well-known to scientists, and was one of the subjects of our first ever efforts to image the cosmic beasts, but its still throwing up new mysteries all the time.After observing for over four days using the Keck II Telescope in Hawaii, a team that has been studying Sagittarius A* for 20 plus years noticed the infrared light increased by 75 times.

Infosys shares continued their downward spiral on Friday to end with a weekly loss of almost 4 percent as investors viewed the company losing its multi-million dollar Royal Bank of Scotland (RBS) project with concern. The BSE Sensex ended 46 points lower at 28,077.The Infosys stock closed at Rs. 1,021.10 on Friday on the Bombay Stock Exchange (BSE), a fall of 3.98 percent from its previous Friday close of Rs. 1,063.30. In intra-day trade, the stock plunged to Rs. 1,019, almost near to its 52-week low of Rs. 1,012.25.Last Saturday (August 13), the Bengaluru-based IT software services exporter had said in a statement that RBS had scrapped a project to spin off and list Williams & Glyn (W&G) as a separate entity. Infosys, along with IBM, had won a project in September 2013 to develop computer systems for W&G for an estimated Rs. 2,500 crore. Infosys had deployed about 3,000 people on the project as the technology partner.”Infosys has been a W&G program technology partner for Consulting, Application Delivery and Testing services, and subsequent to this decision, will carry out an orderly ramp-down of about 3,000 persons, primarily in India, over the next few months,” the company had said in the statement.”The Royal Bank of Scotland announced last week that it will no longer pursue its plan to separate and list a new UK standalone bank, Williams & Glyn (W&G), and instead will pursue other options for the divestment of this business. RBS is a key relationship for Infosys and the company looks forward to further strengthening our strategic partnership and working with them across other strategic and transformation programs,” Infosys added.The BSE Sensex ended with losses on Friday after Thursday’s 118 point rally.Top Sensex losers included Coal India, TCS, Lupin and Wipro, while stocks that lifted the 30-scrip benchmark equity index included State Bank of India (up 4.15 percent at Rs. 258.50), Tata Steel and Cipla. The week saw private sector lender RBL Bank’s initial public offering (IPO) commencing. The public issue will remain open till August 23.The bank raised Rs. 364 crore from anchor investors by issuing shares to 28 anchor investors at the upper price band of Rs 225. The bank’s track record on the loan front is considered sound because of its client profile. “Market experts are of opinion that the bank has stayed away from stressed sectors such as steel, power as well as infrastructure, which has helped it to maintain its asset quality at better levels compared to its peers,” Dynamic Levels said in its IPO note.
The combination of Prime Minister Narendra Modi and BJP president Amit Shah in 2019 may have exorcised the ghosts of the party’s disastrous 2004 ‘India Shining’ campaign.Twitter/IANSExit polls have predicted the return of Prime Minister Narendra Modi to power, sending the markets into a tizzy. The huge majority expected for the Bharatiya Janata Party (BJP)-led National Democratic Alliance (NDA) has spurred the stock markets to new highs. Traders hope that the prospect of the installation of a market-friendly government will bring back the foreign portfolio investors (FPI) that had taken flight during the six-week-long seven-phase election process.The markets are likely to price in the euphoria ahead of the May 23 counting and there is a chance of the volatility peaking. The election outcome is likely to emerge only in a day or two after the counting begins because of the delay in matching the VVPAT (voter-verified paper audit trail) slips with the EVM (electronic voting machine) numbers.The exit polls predict that the NDA could win between 267 and 354 seats in the 543-member Lok Sabha. In contrast, the BJP-led NDA won 336 seats in 2014, as against 60 of the main opposition Congress party-led United Progressive Alliance (UPA) that is projecting Rahul Gandhi as its prime minister candidate. The mish-mash of regional parties and the left outfits won 147 seats in 2014.But the political observers have been right in cautioning the market to temper the euphoria that the exit polls have triggered. They cite the euphoria created by the exit poll predictions of 2004 after the Atal Bihari Vajpayee-led BJP mounted the India Shining campaign. Most major exit polls then suggested that the NDA would come back to power with a wide lead over the Congress-led alliance. Congress president Rahul Gandhi would fervently want to draw parallels between 2004 and 2014 Lok Sabha election campaigns.Of course, the figures that the surveys threw up then were much moderate than the 2019 exit polls. Only Sahara DRS and Star News Cvoter surveys placed NDA beyond the half-way mark of 272 seats. Sahara DRS poll projected a tally of 278 seats for NDA against 181 for the UPA, while Star News CVoter survey gave the NDA 275 seats and UPA 186. In fact, the average of five major surveys predicted 260 seats for the BJP-led front and 188 for the UPA. However, the NDA ended up with 189 seats against the UPA’s 225. The rest is history with two stints of Manmohan Singh as prime minister until the 2014 Modi wave.Some experts point out that exit polls would be closer to the actual results in a less emotionally charged election. This is because exit polls often reflect the voters’ perception of the scenario rather than his or her actual preference. In an atmosphere that is extremely vitiated by the social media and massive campaigns, there is all the more a chance of the voters’ perception being influenced by the last message that got imprinted in the memory.Therefore, veteran traders suggest caution while trading the election news with tight stop-loss settings. The market could see some profit-taking ahead of the results on Thursday, especially after the single day surge of more than 1,400 points to close at 39,352 points of the Bombay Stock Exchange (BSE) benchmark Sensex and 400 points of the National Stock Exchange benchmark Nifty to close at 11,828 points taking the benchmark indices to shouting distances of all-time high points.Of course, 2019 is not exactly 2004 and the combine of Prime Minister Modi and BJP president Amit Shah is not that of Vajpayee and LK Advani. The BJP’s vote share has surged since 2004 and there is no denying that the party has spread into more areas with strong organizational buildups. Therefore, the exit polls this time could hit the bull’s eye.
