Scientists discover exoplanets orbiting both stars of binary system

Worlds without end: Scientists have discovered a stellar binary system which has giant exoplanets orbiting each of the system’s stars.

The twin stars studied by the group are called HD 133131A and HD 133131B. The former hosts two moderately eccentric planets, one of which is, at a minimum, about 1 and a half times Jupiter’s mass and the other of which is, at a minimum, just over half Jupiter’s mass. The latter hosts one moderately eccentric planet with a mass at least 2.5 times Jupiter’s.

The two stars themselves are separated by only 360 astronomical units (AU). One AU is the distance between the Earth and the Sun. This is extremely close for twin stars with detected planets orbiting the individual stars. The next-closest binary system that hosts planets is comprised of two stars that are about 1,000 AU apart.

Dawn moves to higher orbit around Ceres

In order to save fuel as well as obtain a different view of Ceres, engineers are moving Dawn to a higher orbit.

On Sept. 2, Dawn will begin spiraling upward to about 910 miles (1,460 kilometers) from Ceres. The altitude will be close to where Dawn was a year ago, but the orientation of the spacecraft’s orbit — specifically, the angle between the orbit plane and the sun — will be different this time, so the spacecraft will have a different view of the surface.

Big scandal for Virgin Galactic’s investment partner

Virgin Galactic’s biggest investor has been caught up in a big scandal involving two of its top managers, including the arrest of one.

As noted at the link, there is no evidence that anyone at Virgin Galactic was involved in what appears to be an illegal transfer of $3.5 billion from the investment company. However, the collapse of this company, which invested $390 million for a 37% share in Virgin Galactic, could impact the space company’s future efforts.

DNA sequencing successfully done on ISS

Researchers have now confirmed that a new lightweight DNA sequencer has been successfully tested on ISS.

Using a hand-held, USB-powered sequencing device called the MinION, astronaut Kate Rubins, PhD, sequenced samples of mouse, bacteria and virus DNA. This portable sequencing technology could eventually help diagnose sick astronauts, monitor space station food, water, and environment for microbes, and identify extraterrestrial life forms.

As part of a collaboration with NASA on the Biomolecular Sequencer project, Earth-bound researchers – a bicoastal team at UCSF and Weill Cornell Medical College – analyzed the sequencing data from space and compared it to identical samples sequenced on the ground. The analysis would tell whether the journey to space and conditions aboard the space station affected the sequencing results.

…[An] analysis of the space and Earth data found comparable results. “We essentially got equivalent data, and it’s of very high quality, probably within the top 20 percent of nanopore runs that we do routinely here on Earth,” Chiu said.

The press release makes a big deal about how this new equipment will be beneficial for research in space, but I am betting that its creators are as much if not more interested in the profits they will make selling it to customers on Earth, where its portability will make a very useful and beneficial to Earth-bound patients and researchers.

Three professors ban skepticism of human-caused climate change

Academic fascists: Three professors teaching an online course at the University of Colorado-Colorado Springs have told their students that they are forbidden to raise any skeptical data or sources or even questions when the issue of man-made global warming is discussed.

Signed by the course’s professors Rebecca Laroche, Wendy Haggren and Eileen Skahill, it was sent after several students expressed concern for their success in the course after watching the first online lecture about the impacts of climate change. “Opening up a debate that 98% of climate scientists unequivocally agree to be a non-debate would detract from the central concerns of environment and health addressed in this course,” the professors’ email continued. “… If you believe this premise to be an issue for you, we respectfully ask that you do not take this course, as there are options within the Humanities program for face to face this semester and online next.”

The professors also note this ban on debate extends to discussion among students in the online forums. Moreover, students who choose to use outside sources for research during their time in the course may select only those that have been peer-reviewed by the Intergovernmental Panel on Climate Change, the email states.

Putting aside the fact that the study claiming that 97% of scientists agree with man-made global warming has been debunked, this refusal to allow open debate by these fake teachers makes them the poster child for fascism in academia.

An update on Stereo-B’s status

The engineers working to recover Stereo-B, the solar observatory that was lost for 22 months, have released an update on the spacecraft’s condition.

In the subsequent days, analysis revealed the spacecraft was in a complex spin, with its fuel tanks frozen and the battery state of charge at 30%. The prime goal is now to fully recover battery power and gradually thaw STEREO-B’s instruments and fuel tanks from its deep freeze. It may be clear that the spacecraft is still in a critical condition and that it will take quite some time before imagery, such as those from its twin STEREO-A, will be available again.

If you are interested in more details, go to the Stereo-B update website, where they are posting almost daily reports.

Third Lunar X-prize competitor signs launch contract

The competition heats up: The Google Lunar X-prize has confirmed that a third competitor, Synergy Moon, has signed a launch contract to send its privately built and funded rover to the Moon.

The Synergy Moon mission will use a Neptune 8 rocket, built and launched by Interorbital Systems, to carry a lunar lander and at least one rover to the surface of the moon, launching from an open-ocean location off the California coast during the second half of 2017. Team Synergy Moon is one of three Google Lunar X-Prize teams now set to compete in 2017, joining SpaceIL and Moon Express. The remaining 13 teams have until December 31, 2016 for their launch agreements to be verified by X-Prize in order to proceed in the competition.

In looking at the website of the launch company, I am not impressed. I hope they succeed, but I would not put much money on this Lunar X-Prize competitor.

Richard Feynman explains the Scientific Method

An evening pause: During last week’s failed attempts to explain the concept of doubt and skepticism in science to a global warming adherent (which begins here and also in the comments of this post), Edward Thelen provided a link to the video below of one of Richard Feynman’s lectures. I thought it entertaining enough to be an evening pause, and educational enough that more people should see it. Listen especially near the middle when he begins to talk about the uselessness of theories that are vague and poorly defined. It will strike a nerve if you have been paying attention to the climate debates during the past two decades.

Michigan court rules against civil forfeiture

Good news: The Michigan Court of Appeals has ruled that civil forfeiture denies citizens their due process rights under the Constitution. As the court wrote:

“Because of her indigency and inability to pay the required bond, [Kinnon] was excluded ‘from the only forum effectively empowered to settle [her] dispute.’ … Ultimately, Michigan’s civil asset forfeiture scheme operated to deprive [Kinnon] of a significant property interest without according her the opportunity for a hearing, contrary to the requirements of the Due Process Clause.”

This shouldn’t be rocket science, as the language and intent of the Fifth Amendment to the Constitution is quite plain.

No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.

The problem today is that this has become rocket science. Too many people either don’t know this plain language, or work dishonestly to distort it to empower government to oppress us.

Obama to ratify Paris climate treaty, bypassing Senate

The Constitution is such an inconvenient thing: The Obama administration is claiming that, should Obama sign the Paris climate accords when he visits China next week, it will be sufficient to make it law, even though it will not have been approved by a two-thirds majority in the Senate as required by the Constitution.

White House senior adviser Brian Deese said the president has the legal authority to ratify the accord without the two-thirds Senate vote required for treaties. He said the pact negotiated by 195 countries in December is merely an “executive agreement. … The president will use his authority that has been used in dozens of executive agreements in the past to join and formally deposit our instrument of acceptance, and therefore put our country as a party to the Paris Agreement,” Mr. Deese said at a White House press conference. “That’s a process that is quite well-established in our existing legal system and in the context of international agreements and international arrangements,” Mr. Deese said. “There is a category of them that are treaties that require advice and consent from the Senate, but there’s a broad category of executive agreements where the executive can enter into those agreements without that advice and consent.”

Gee, I wonder what clause in the Constitution Mr. Deese can name that delineates the President’s power to sign and make binding “executive agreements” with foreign powers? My copy of the Constitution doesn’t seem to have any such clause. What it does say about foreign treaties is quite clear and blunt: The President “shall have Power, by and with the Advice and Consent of the Senate, to make Treaties, provided two-thirds of the Senators present concur.” (Article 2, Section 2).

But then, when has the law ever really meant anything to this President and the modern Democratic Party? In fact, it means so little to them that they have nominated a candidate for President who willfully ignores it, and then lies about that lawbreaking repeatedly.

Russian hackers attack US election systems

What, me worry? Russian hackers attempted and were partly successful in June in accessing the election databases of Arizona and Illinois.

Hackers targeted voter registration systems in Illinois and Arizona, and the FBI alerted Arizona officials in June that Russians were behind the assault on the election system in that state. The bureau described the threat as “credible” and significant, “an eight on a scale of one to 10,” Matt Roberts, a spokesman for Arizona Secretary of State Michele Reagan (R), said Monday. As a result, Reagan shut down the state’s voter registration system for nearly a week.

It turned out that the hackers had not compromised the state system or even any county system. They had, however, stolen the username and password of a single election official in Gila County.

The article describes in detail the overall bad situation, including a number of additional attacks as well as the poor security surrounding the online voting option that more than 30 states use.

As usual, we are being told not to worry by the responsible government officials:

Tom Hicks, chairman of the federal Election Assistance Commission, an agency set up by Congress after the 2000 Florida recount to maintain election integrity, said he is confident that states have sufficient safeguards in place to ward off attempts to ma­nipu­la­te data. For example, if a voter’s name were deleted and did not show up on the precinct list, the individual could still cast a provisional ballot, Hicks said. Once the voter’s status was confirmed, the ballot would be counted. Hicks also said the actual systems used to cast votes “are not hooked up to the Internet” and so “there’s not going to be any ma­nipu­la­tion of data.” However, more than 30 states have some provisions for online voting, primarily for voters living overseas or serving in the military.

Hicks has made me feel so much better!
