Free E-book From NASA on Dark Matter & Dark Energy

Posted on by onespaceman2000

NASA has released a free e-book titled Hubble Focus: The Dark Universe. You can download the book at the NASA site in one of two formats – PDF or EPUB. This is the fifth edition of this book.

You cannot argue with the price, while the content is an impressive story about how the Hubble Space Telescope has helped to study both dark matter and dark energy. In addition to the text and images, the book contains links to numerous videos that further illustrate the points in the book. It is a multimedia experience that can only enhance your understanding of the topic.

Hubble is just the beginning, as the James Webb Space Telescope and other instruments are coming online to assist with the research. The book notes:

Hubble continues to be a vital tool to address questions about the underlying workings of the universe . Scientists will pair its wide wavelength coverage with James Webb Space Telescope’s powerful vision, the upcoming Nancy Grace Roman Space Telescope’s panoramic view, and a fleet of additional space- and ground-based telescopes to explore the cosmos as never before . We have far more left to learn among the stars

Space Quote: Japanese Prime Minister Channels Star Trek

Posted on by onespaceman2000

“We are now standing at a turning point in history, embarking on a new frontier, and elevate this unshakable Japan-US relationship to even greater heights and hand it to the next generation. Finally, let me be conclude with a line from Star Trek, which you all know: To boldly go where no one has gone before.”

–Statement by Japanese Prime Minister Fumio Kishida at a White House state dinner on Wednesday. He was quoting part of the famous opening credits in the Star Trek television series:

These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds; to seek out new life and new civilizations; to boldly go where no man has gone before!

Oops – Sorry About That, Mars

You may remember how NASA’s Double Asteroid Redirection Test (DART) mission was a great success in that it demonstrated that we can divert an asteroid, should it be necessary.

Well, that’s not the whole story. A new study has found that the redirected asteroid debris may threaten Mars in the future. How far into the future? In one case, it will be 6,000 years into the future, and the second about 15,000 years into the future.

It would be nice to think that we will have habitats if not cities on Mars at that point (and maybe even a Musk Mountain looming over one of the cities), so this could be relevant. So maybe today’s practice run will be tomorrow’s disaster. Then again, I am pretty sure that such a future society will also have the ability to deflect these asteroids, possible building on what we learned from DART.

All of this does make you think about other areas where our tampering may come back to bite us.

Pic of the Week: The Total Solar Eclipse

The image of the week relates to the Total Solar Eclipse that captured the nation’s attention. Goofy glasses like the ones shown in The Chicago Tribune (above) and Wired magazine (below) were worn across the country to watch this rare event.

A UFO on the Moon?

The grainy image above may remind you of some of the UFO images that circulated years ago. However, in this case, the image is from the Moon as captured by NASA’s Lunar Reconnaissance Orbiter.

What you are seeing is a Korean spacecraft going thousands of miles per hour (hence the blurred, elongated image). Named the Korea Pathfinder Lunar Orbiter (KPLO), or the Danuri, the spacecraft is part of South Korea’s first lunar mission launched in August 2022. Korea is the seventh nation to send an orbiter to the Moon.

Below is an image of the KPLO minus the blurring speed. The spacecraft was designed to orbit the Moon for one year collecting data, though it is still going strong after hitting its year anniversary back in December. As part of its mission, it is carrying a NASA camera, the ShadowCam, to observe shadowed areas on the Moon.

The Moon is a busy place these days.
