Hubble telescope celebrates 28 years in space with a dip in the dazzling Lagoon Nebula
Hubble telescope celebrates 28 years of being a space sleuth with these dazzling images of the Lagoon Nebula, 4,000 light-years away.
Hubble was launched on April 24, 1990, about the space shuttle Discovery. Every year since, scientists at NASA, together with the European Space Agency (ESA), release spectacular images from it to recognize its "birthday."
The Lagoon Nebula is a hub of stars being born, and it’s 55 light-years wide and 20 light-years tall.
NASA and ESA officials wrote an apt message about the nebula being imaged. ”Even though it is about 4,000 light-years away from Earth, it is three times larger in the sky than the full moon. It is even visible to the naked eye in clear, dark skies. Since it is relatively huge on the night sky, Hubble is only able to capture a small fraction of the total nebula."
For its part, the aging telescope has undergone five repairs and upgrades in space, the last in 2009. It’s expected to last until at least 2020, and likely longer.
The successor to Hubble, the $8.8 billion James Webb Space Telescope, is scheduled to launch in Spring of 2020.
Here are two images and a tantalizing video released in honor of Hubble's 28th year in space. Happy birthday, old friend!
The video is also quite captivating; there are more located here.
The pandemic reminds us that our higher education system, with all its flaws, remains a key part of our strategic reserve.
- America's higher education system is under great scrutiny as it adapts to a remote-learning world. These criticisms will only make higher ed more innovative.
- While there are flaws in the system and great challenges ahead, higher education has adapted quickly to allow students to continue learning. John Katzman, CEO of online learning organization Noodle Partners, believes this is cause for optimism not negativity.
- Universities are pillars of scientific research on the COVID-19 frontlines, they bring facts in times of uncertainty and fake news, and, in a bad economy, education is a personal floatation device.
Meteorologists propose a stunning new explanation for the mysterious events in the Bermuda Triangle.
One of life's great mysteries, the Bermuda Triangle might have finally found an explanation. This strange region, that lies in the North Atlantic Ocean between Bermuda, Miami and San Juan, Puerto Rico, has been the presumed cause of dozens and dozens of mind-boggling disappearances of ships and planes.
An MIT system uses wireless signals to measure in-home appliance usage to better understand health tendencies.
For many of us, our microwaves and dishwashers aren't the first thing that come to mind when trying to glean health information, beyond that we should (maybe) lay off the Hot Pockets and empty the dishes in a timely way.
Online dating has evolved, but at what cost?
- Some dating apps allow individuals to interact and form romantic/sexual connections before meeting face to face with the ability to "swipe" on the screen to either accept or reject another user's profile. Popular swipe-based apps include Tinder, Bumble, and OkCupid.
- Research by Western Sydney University and the University of Sydney has linked the experience of swipe-based dating apps to higher rates of psychological distress and/or depression.
- Not all time spent on these apps is damaging, however. Up to 40 percent of current users say they previously entered a serious relationship with someone they met through one of these apps.
