The Death of Arecibo

Apparently, the radio telescope at Arecibo is no more. According to This item on the radio telescope has completely collapsed.

“The telescope’s 900-ton receiver platform and the Gregorian dome—a structure as tall as a four-story building that houses secondary reflectors—fell onto the northern portion of the vast reflector dish more than 400 feet below.

The U.S. National Science Foundation had earlier announced that it would close the radio telescope. An auxiliary cable snapped in August, causing a 100-foot gash on the 1,000-foot-wide (305-meter-wide) dish and damaged the receiver platform that hung above it. Then a main cable broke in early November.

The collapse stunned many scientists who had relied on what was until recently the largest radio telescope in the world.”

This has been a long time coming according to this story from 2017 . Nonetheless, I still find it incredibly sad.

Bacteria Made Of Star Stuff

One of the best at explaining science was Carl Sagan. One recurring theme in Sagan’s works can be seen in the quote below:

And we who embody the local eyes and ears and thoughts and feelings of the cosmos we’ve begun, at last, to wonder about our origins. Star stuff, contemplating the stars organized collections of 10 billion-billion-billion atoms contemplating the evolution of matter tracing that long path by which it arrived at consciousness here on the planet Earth and perhaps, throughout the cosmos.

The Big Bang and Beyond

Starts with a Bang has an very interesting post on the Big Bang called How Sure are we that the Big Bang is Correct? and after reading that, you should check out Echoes Of The Birth Of The Universe: New Limits On Big Bang’s Gravitational Waves at Science Daily.

Monkeys in Space!

I don’t know how I missed this, but yesterday was the 50th anniversary of the launching of Baker (a squirrel monkey) and Abel (a rhesus monkey) into space. They were the first primates to survive a trip into space (although Abel died a few days after the trip due to an infected electrode. National Geographic has some pictures to commemorate the event.

In other primate related news, I have managed to injure my right hand and wrist (more about that later) so blogging may be light for the next couple of days.

Update 1: Turns out I have a sprain of the right wrist, makes typing a bit difficult…

Model Gives Clearer Idea Of How Oxygen Came To Dominate Earth’s Atmosphere
Researchers interested in how earth’s atmosphere came to be dominated by oxygen have come up with an interesting model to explain why there was a lag between the origin of photosynthesis and the domination of earth’s atmosphere by oxygen.
There were several processes at work. First, gasses emitted from volcanoes combined with the oxygen and acted as an oxygen sink. Second, oxidation of iron from space bombardment acted as a second sink. Researcers found that varying the estimates of iron content in the earth’s crust could change the time frame by up to a billion years in one direction or the other.

Hubble Telescope: Happy Sweet Sixteen!

The Hubble Telescope turned 16 today. To celebrate, this cool picture of Messier 82 – a galaxy some 12 million light-years away – was released ba NASA.

The Future of Space Science: Depressing

According to New Scientist the fate of NASA’s science budget is pretty gloomy:

NASA’s proposed cuts to its science budget will have a devastating impact on astronomy and Earth-science research for years to come, an expert panel told a US congressional committee on Thursday.
Panellists urged NASA to restore funding for research and analysis grants, and low-cost missions – even if that comes at the expense of more ambitious missions, such as the James Webb Space Telescope.
