Astronomer: Look for monolith on co-orbiting asteriods

5:37 pm

According to one astronomer in a paper published this week, the most likely place to find alien artifacts would be on the co-orbital asteroids, objects whose orbit is very similar to the Earth and thus always nearby but mostly unseen.

In this context, a co-orbital is an asteroid that goes around the Sun on the same, or similar, orbital path to Earth. Co-orbital objects approach Earth very closely every year at distance is much shorter than anything except the moon.

Consequently, co-orbitals could be a great place to watch Earth from. Not only would any alien probes on co-orbital objects be concealed, but they would also be anchored and able to access solar energy. They could possibly sustain themselves for many thousands of years.

According to this paper, if aliens have visited the solar system in the past they would place their long-term alien probes on such an asteroid, or even give it a comparable co-orbit. And if we look and don’t find anything, that would strongly imply that we are alone in the universe.

Fun stuff, but need I say that not finding alien artifacts at these locations proves nothing.

The mystery of Tabby’s Star deepens

11:15 pm

The uncertainty of science: New data from Kepler has made it even more difficult for scientists to explain the strange fluctuations and dimming of Tabby’s Star.

KIC 8462852, as it is more properly known, flickers so erratically that one astronomer has speculated that nothing other than a massive extraterrestrial construction project could explain its weird behaviour. A further look showed it has been fading for a century. Now, fresh analysis suggests the star has also dimmed more rapidly over the past four years – only adding to the enigma. “It seems that every time someone looks at the star, it gets weirder and weirder,” says Benjamin Montet at the California Institute of Technology, who led the study.

There are as yet no natural explanations for the star’s dimming.

How to really look for aliens

11:38 am

Two scientists summarize the challenge for finding alien life in the universe.

Look for high amounts of oxygen and mid-infrared energy, the second of which has already produced some candidates.

A recent large survey by the Wide-field Infrared Survey Explorer (WISE) satellite did identify five red spiral galaxies whose combination of high MIR and low near-ultraviolet luminosities are inconsistent with simple expectations from high rates of star formation. A conventional explanation for these observations, such as the presence of large amounts of internal dust, has not been ruled out, however. Such peculiar objects deserve follow-up observations before we explore whether they might represent the signatures of galaxy-dominating species.

The article is very thoughtful, however, and outlines in detail the issues and problems the research faces. We might, in a few decades, have the capability to answer this question, but then, the aliens might be alien enough to still be undetectable. Or they might not exist at all.

Hillary Clinton vows to investigate UFOs if elected

8:55 am

Well, we now know her priorities! In a meeting with the editorial board of a New Hampshire newspaper, Democratic presidential candidate Hillary Clinton vowed to find out once and for all whether UFOs have been discovered by the federal government and kept secret.

Her husband Bill Clinton apparently tried and failed to uncover those buried records while he was President.

I am sure this reassures you all. While the Republicans are distracted by unimportant issues, such as terrorism, radical Islam, a weak economy, an out-of-control federal budget, and a corrupt federal bureaucracy that is abusing its power while failing to do its job, Hillary Clinton has her sights on issues of real importance.

Kepler finds a star no one can explain

3:56 pm

Observations using Kepler have uncovered a star whose light fluctuations can only be explained in two ways.

First,

If another star had passed through the unusual star’s system, it could have yanked a sea of comets inward. Provided there were enough of them, the comets could have made the dimming pattern. But that would be an extraordinary coincidence, if that happened so recently, only a few millennia before humans developed the tech to loft a telescope into space. That’s a narrow band of time, cosmically speaking.

Second? Maybe the star’s light is being blocked by a swarm of megastructures built by an alien civilization. They intend to look for radio emissions from the star in wavelengths associated with technology to see if this theory has any possibility.

UN to appoint astrophysicist to negotiate with aliens

1:37 am

The United Nations in charge! They have decided that — should extra-terrestrials ever arrive on Earth — an obscure Malaysian astrophysicist/UN bureaucrat must be in charge of negotiations. In her words:

“We should have in place a co-ordinated response that takes into account all the sensitivities related to the subject. The UN is a ready-made mechanism for such co-ordination.”
