This new Hubble image shows IRAS 14568-6304, a young star that is cloaked in a haze of golden gas and dust. It appears to be embedded within an intriguing swoosh of dark sky, which curves through the image and obscures the sky behind. This dark region is known as the Circinus molecular cloud. This cloud has a mass around 250 000 times that of the Sun, and it is filled with gas, dust and young stars. Within this cloud lie two prominent and enormous regions known colloquially to astronomers as Circinus-West and Circinus-East. Each of these clumps has a mass of around 5000 times that of the Sun, making them the most prominent star-forming sites in the Circinus cloud. The clumps are associated with a number of young stellar objects, and IRAS 14568-6304, featured here under a blurry fog of gas within Circinus-West, is one of them. IRAS 14568-6304 is special because it is driving a protostellar jet, which appears here as the "tail" below the star. This jet is the leftover gas and dust that the star took from its parent cloud in order to form. While most of this material forms the star and its accretion disc — the disc of material surrounding the star, which may one day form planets — at some point in the formation process the star began to eject some of the material at supersonic speeds through space. This phenomenon is not only beautiful, but can also provide us with valuable clues about the process of star formation. IRAS 14568-6304 is one of several outflow sources in the Circinus-West clump. Together, these sources make up one of the brightest, most massive, and most energetic outflows ever reported. Scientists have even suggested calling Circinus-West the "nest of molecular outflows" in tribute to this activity. A version of this image was entered into the Hubble's Hidden Treasures image processing competition by contestant Serge Meunier.
Where are our petabyte drives? Brian Hayes takes us through the reasons storage is “stuck” in the low terabytes. The tl;dr is that we got such exceptional capacity growth in the late 90s and early 00s we don’t need much more right now, so the focus since then has been on SSDs, networking, interfaces, etc, […]
Amélie Lamont, a former staffer at website-hosting startup Squarespace, writes that she often found herself disregarded and disrespected by her colleagues. One comment in particular, though, set her reeling — and came to exemplify her experiences there.

Some truths are universal. For one, your phone will always run out of power when you most need it. For another, the charging cords that come packaged with your Apple device will fray, split, and rip faster than Usain Bolt in a game of tag.Instead, pick up a charging cord that anyone would have a tough […]
Some people say magic tricks are nerdy and best left to your 12-year-old asthmatic cousin. But others see value in perfecting the slight of hand and showmanship associated with a perfectly executed routine. We’re firmly in the latter camp. And now, we’re giving you the ability to put a few parlor tricks up your sleeve with the Penguin […]
Bluetooth speakers may be convenient to use, but many of them just aren’t that powerful. Sure, it may be fine if you’re seated in front of the speaker. But move across the room, and you may strain to hear what’s coming from those tiny drivers.There’s a reason why the G-BOOM Wireless Bluetooth Boombox (now $79.99 in the Boing […]
