Gravitational waves from early universe remain elusive

more »

A joint analysis of data from the Planck space mission and the ground-based experiment BICEP2 has found no conclusive evidence of gravitational waves from the birth of our universe, despite earlier reports of a possible detection. The collaboration between the teams has resulted in the most precise knowledge yet of what signals from the ancient gravitational waves should look like, aiding future searches.

Three hot blobs of matter orbiting a black hole. If placed in our Solar System, this black hole would appear like a dark abyss spread out nearly as wide as Mercury's orbit. And the three blobs (each as large as the Sun) would be as far out as Jupiter. They orbit the black hole in a lightning-quick 20,000 miles per second, over a tenth of the speed of light.

Relax, your sexual fantasies aren't that strange

Science Focus

original post »

Do you ever wonder about your sexual fantasies, and what they say about you? If so, one of two worries likely comes to mind: "Am I really this conventional and boring?" or "Does the fact I'm having these thoughts mean I'm abnormal?"

Newly published research suggests you can relax. It finds humans indulge in a wide range of erotic fantasies, only a handful of which fall on either extreme (that is, almost everyone has experienced them, or almost no one has).

"There are very few statistically unusual sexual fantasies," reports a research team led by Canadian psychologist Christian Joyal. Its paper is published in the Journal of Sexual Medicine.

Joyal and his colleagues conducted a detailed online survey of 1,516 adults. (While that's a large sample, the researchers concede that people willing to share their sexual fantasies aren't necessarily representative of the general population.)

Participants were presented with a list of 55 sexual fantasies. They were asked to rate each on a one-to-seven scale, one being it doesn't excite them at all, and seven representing a very strong response.

They were also asked to write down their favorite sexual fantasy if it was not included among the 55. Three hundred and seventy-two people did so.

Of the 55 fantasies, only two were found to be "statistically rare" (that is, endorsed by 2.3 percent or less of participants): Having sex with a child under age 12, and having sex with an animal. Another nine were "statistically unusual" (endorsed by 15.9 percent or less of participants); "urinating on partner" fell into this category.

At the other end of the spectrum, only three sexual fantasies were statistically typical for both men and women (endorsed by more than 84.1 percent of participants): feeling romantic emotions during a sexual relationship, fantasies in which atmosphere and location are important, and fantasies involving a romantic location.

Two additional fantasies were typical for males only: "Receiving oral sex, and having sexual intercourse with two women."

"The proportion of women acknowledging submissive fantasies is not negligible," the researchers write. "Being sexually dominated (64.6 percent), being tied up for sexual pleasure (52.1 percent), being spanked or whipped (36.3 percent), and being forced to have sex (28.9 percent) were all reported by significant proportions of women."

"Interestingly, the same sexual fantasies were also reported by significant proportions of men (53.2, 46.2, and 3.7 percent respectively)," they add. "The fantasy of being dominated was significantly greater for women than for men, on average, whereas the fantasy of dominating was statistically stronger for men than for women, on average."

Overall, "reports of submission fantasies were significantly associated with reports of domination fantasies," they add, "indicating that these fantasy themes are not separate or in opposition."

While these results explain the popularity of Fifty Shades of Grey, it doesn't mean men should assume prospective partners are looking to get spanked.

"Approximately half of women with descriptions of submissive fantasies specified that they would not want their fantasy to materialize in real life," the researchers write. "This result confirms the important distinction between sexual fantasies and sexual wishes, which is usually stronger among women than among men."

One additional intriguing finding: "The percentages of women and men fantasizing about homosexual activities significantly exceeded the percentages of declared bisexuality or homosexuality."

Hmm. Even in this era of gay marriage, could it be that a stigma still surrounds homosexuality, leading some to fantasize about such activity, but refrain from defining themselves as gay?

With Lee Hutchinson about to grab the mic and tell us about visiting Munich, we're wrapping up my time in the spotlight by doing a live Q&A. At 1pm Eastern tomorrow, I'll set up a live chat and field questions about anything that interests you, from sichuan peppers to real-time control software. I'd also be happy to talk a bit about the differences between academic and commercial research, as well as the challenges of making sure that the results of your research can be mass produced.

If people have questions about science, or the challenges of writing about it, I'd be happy to field those, too. So stop by tomorrow and say hi.

Monogram Carina Nebula - Breathtaking Universe Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: stlrnrsry, star clusters, galaxies, stars, starfields, awesome astronomy pictures, constellation puppis, the stern, monogram, monograms, star nurseries, nebulae, european southern observatory, eso, vista, initials, initialled, monogrammed

Galaxies, Stars and Nebulae series

A gorgeous set of oval stickers showing the area surrounding the stellar cluster NGC 2467, located in the southern constellation of Puppis ("The Stern"). With an age of a few million years at most, it is a very active stellar nursery, where new stars are born continuously from large clouds of dust and gas.

The image, looking like a colourful cosmic ghost or a gigantic celestial Mandrill, contains the open clusters Haffner 18 (centre) and Haffner 19 (middle right: it is located inside the smaller pink region - the lower eye of the Mandrill), as well as vast areas of ionised gas.

The bright star at the centre of the largest pink region on the bottom of the image is HD 64315, a massive young star that is helping shaping the structure of the whole nebular region.

Yellow Balls in W33

more »
Infrared wavelengths of 3.6, 8.0, and 24.0 microns observed by the Spitzer Space Telescope are mapped into visible colors red, green, and blue in this striking image. The cosmic cloud of gas and dust is W33, a massive starforming complex some 13,000 light-years distant, near the plane of our Milky Way Galaxy. So what are all those yellow balls? Citizen scientists of the web-based Milky Way Project found the features they called yellow balls as they scanned many Spitzer images and persistently asked that question of researchers. Now there is an answer. The yellow balls in Spitzer images are identified as an early stage of massive star formation. They appear yellow because they are overlapping regions of red and green, the assigned colors that correspond to dust and organic molecules known as PAHs at Spitzer wavelengths. Yellow balls represent the stage before newborn massive stars clear out cavities in their surrounding gas and dust and appear as green-rimmed bubbles with red centers in the Spitzer image. Of course, the astronomical crowdsourcing success story is only part of the Zooniverse. The Spitzer image spans 0.5 degrees or about 100 light-years at the estimated distance of W33.

In the Shadow of Saturn Poster

Here's a great poster featuring a beautiful image from deep space


tagged with: shadow, saturn, nasa, outer, space, universe, galaxy, astronomy, solar, system, eclipse, sun, cassini, ring, new, rings, earth, color

In the shadow of Saturn, unexpected wonders appear. The robotic Cassini spacecraft now orbiting Saturn recently drifted in giant planet's shadow for about 12 hours and looked back toward the eclipsed Sun. Cassini saw a view unlike any other. First, the night side of Saturn is seen to be partly lit by light reflected from its own majestic ring system. Next, the rings themselves appear dark when silhouetted against Saturn, but quite bright when viewed away from Saturn and slightly scattering sunlight, in the above exaggerated color image. Saturn's rings light up so much that new rings were discovered, although they are hard to see in the above image. Visible in spectacular detail, however, is Saturn's E ring, the ring created by the newly discovered ice-fountains of the moon Enceladus, and the outermost ring visible above. Far in the distance, visible on the image left just above the bright main rings, is the almost ignorable pale blue dot of Earth. Credit: CICLOPS, JPL, ESA, NASA

Monogrammed Helix Nebula, Galaxies and Stars Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: star nurseries, star clusters, galaxies, stars, astronomy, nebulae, helixneb, helix nebula, initialled, monogrammed, starfields, heavens, eso, european southern observatory, vista, monogram, initials, monograms

Galaxies, Stars and Nebulae series A fantastic colour-composite image of the Helix Nebula (NGC 7293). It was created from images obtained using the Wide Field Imager (WFI), an astronomical camera attached to the 2.2-metre Max-Planck Society/ESO telescope at the La Silla observatory in Chile.

The blue-green glow in the centre of the Helix comes from oxygen atoms shining under effects of the intense ultraviolet radiation of the 120 000 degree Celsius central star and the hot gas.

Further out from the star and beyond the ring of knots, the red colour from hydrogen and nitrogen is more prominent. A careful look at the central part of this object reveals not only the knots, but also many remote galaxies seen right through the thinly spread glowing gas.
