Mark Zuckerberg Again Rejects Claims Of Facebook Impact On US Election

Hyderabad, May 6: Away from city lights, two hours before Sunrise, people in India and across the world can witness Annual Meteor Shower called Eta Aquarids till May 28.

Observed since time immemorial, Meteor shower are commonly known as shooting stars which are nothing but dust flakes of comet/asteroid entering earth atmosphere.

This Annual Eta Aquarids Meteor Shower peaked on Wednesday at 02.30 am on Wednesday whereas presence of Full Moon was an obstacle outshining bright streaks of lights of this meteor shower zipping across the South Eastern sky.

As this meteor shower is active till May 28, people can still watch this celestial spectacle in early morning every day, Planetary Society of India (PSI) Director N Sri Raghunandan Kumar interacting with UNI said.

As per International Meteor Organization (IMO), 50 meteors per hour are expected to be seen on day of peak today. And this number would vary as days pass on till May 28 while earth passes through dust cloud of comet debris in its orbit.

Washington D.C., Feb 6: An international team of astronomers has found an unusual monster galaxy that existed about 12 billion years ago when the universe was only 1.8 billion years old.

The team of astronomers was led by scientists at the University of California, Riverside.

Dubbed XMM-2599, the galaxy formed stars at a high rate and then died. Why it suddenly stopped forming stars is unclear.

"Even before the universe was 2 billion years old, XMM-2599 had already formed a mass of more than 300 billion suns, making it an ultra massive galaxy," said Benjamin Forrest, a postdoctoral researcher in the UC Riverside Department of Physics and Astronomy and the study's lead author.

"More remarkably, we show that XMM-2599 formed most of its stars in a huge frenzy when the universe was less than 1 billion years old and then became inactive by the time the universe was only 1.8 billion years old," Forrest added.

The team used spectroscopic observations from the W. M. Keck Observatory's powerful Multi-Object Spectrograph for Infrared Exploration or MOSFIRE, to make detailed measurements of XMM-2599 and precisely quantify its distance.

The study results appear in the Astrophysical Journal.

"In this epoch, very few galaxies have stopped forming stars, and none are as massive as XMM-2599," said Gillian Wilson, a professor of physics and astronomy at UCR in whose lab Forrest works.

"The mere existence of ultramassive galaxies like XMM-2599 proves quite a challenge to numerical models. Even though such massive galaxies are incredibly rare at this epoch, the models do predict them."

"The predicted galaxies, however, are expected to be actively forming stars. What makes XMM-2599 so interesting, unusual, and surprising is that it is no longer forming stars, perhaps because it stopped getting fuel or its black hole began to turn on. Our results call for changes in how models turn off star formation in early galaxies," the professor stated.

The research team found XMM-2599 formed more than 1,000 solar masses a year in stars at its peak of activity -- an extremely high rate of star formation. In contrast, the Milky Way forms about one new star a year.

"XMM-2599 may be a descendant of a population of highly star-forming dusty galaxies in the very early universe that new infrared telescopes have recently discovered," said Danilo Marchesini, an associate professor of astronomy at Tufts University and a co-author on the study.

"We have caught XMM-2599 in its inactive phase," Wilson said, who led the W. M. Keck Observatory data acquisition
Co-author Michael Cooper, a professor of astronomy at UC Irvine, said this outcome is a strong possibility.

"Perhaps during the following 11.7 billion years of cosmic history, XMM-2599 will become the central member of one of the brightest and most massive clusters of galaxies in the local universe," he said.

"Alternatively, it could continue to exist in isolation. Or we could have a scenario that lies between these two outcomes," he stated.

The study was supported by grants from the National Science Foundation and NASA.

Washington D.C., Jan 12: A recent study has claimed that people end up wasting almost an entire day when they take a vacation.

This can happen while standing in a queue or searching for places to visit, people do not keep a count of the time they have actually utilised during the trip. As a result, they end up doing much lesser activities than they originally had planned.

According to a recent report in Fox News, the study has also shared the fact that people try to justify time waste with planning and scheduling activities whereas the truth is that these things can be done well ahead to save time during the trip.

The average time waste according to the study commissioned by Sykes Holiday Cottages also said the people taking a seven days' trip waste a minimum of 17-and-a-half hours to figure out various factors.

But there are other causes involved as well. When one visits any crowded location, the real-time spent to enjoy the location is lesser than the time spent on reaching and trying to get involved. For instance, if one visits an amusement park, the activities take lesser time than the preparatory and other phases.
