Peculiar Galaxies of Arp 273

The spiky stars in the foreground of this backyard telescopic frame are well within our own Milky Way Galaxy. But the two eye-catching galaxies lie far beyond the Milky Way, at a distance of over 300 million light-years. Their distorted appearance is due to gravitational tides as the pair engage in close encounters. Cataloged as Arp 273 (also as UGC 1810), the galaxies do look peculiar, but interacting galaxies are now understood to be common in the universe. Nearby, the large spiral Andromeda Galaxy is known to be some 2 million light-years away and approaching the Milky Way. The peculiar galaxies of Arp 273 may offer an analog of their far future encounter. Repeated galaxy encounters on a cosmic timescale can ultimately result in a merger into a single galaxy of stars. From our perspective, the bright cores of the Arp 273 galaxies are separated by only a little over 100,000 light-years.

It seems that in the future people will be able to control their dreams. Researchers at the MIT conducted several studies on this topic. For example, they created a "smart" sleep glove. When you wear it while sleeping sensors record your muscle movements, heartbeat and electrical activity in your skin.

Then this device analyzes all the incoming data and accurately determines which sleeping phase you are in. At the right moment, the device emits a quiet sound signal - for example, the word "bunny"... And a bunny will suddenly appear in your dream. And it really works! The glove has been tested on 50 volunteers.

Is it good or not? Time will tell. Just imagine how they'll use that technology in an advertisement industry. The companies will get a chance to interfere your dream with «drive only BMW» - and you will.

Scientists now predict Earth's temperature will break 1.5C between 2023 and 2027

Which could lead to massive heat waves and elevated sea levels ?
