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.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?
- During the Vietnam War, Robert McNamara began a program called Project 100,000.
- The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
- Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.
The 116th Congress is set to break records in term of diversity among its lawmakers, though those changes are coming almost entirely from Democrats.
- Women and nonwhite candidates made record gains in the 2018 midterms.
- In total, almost half of the newly elected Congressional representatives are not white men.
- Those changes come almost entirely from Democrats; Republican members-elect are all white men except for one woman.
