Astronomers have discovered a planet in the signs of the emerging star system TW Hydra, the young nearby stars, using a radio telescope Atacama Large Millimeter / submillimeter Array (ALMA). Based on the distance from the central star and the distribution of tiny dust particles, the researchers calculated that this planet is likely a giant ice, like Uranus and Neptune in our solar system. This result is another important step towards the understanding of the various classes of planets.

After the most accurate measurement to date of the content of isotopes in lunar samples, geochemists US denied the most common theory of the formation of the moon and made a strong evaporation of the planet in the past. These data indicate almost the same content of varieties of atoms in the samples from the satellite and the planet, indicating their common origin. Tiny differences in the distribution of isotopes of potassium between the substance of the Moon and the Earth were below the limits of detection of the analytical methods until recently. However, a geochemist at the University of Washington in St. Louis Kun Wang and Stein Jacobsen, professor of geochemistry from Harvard University, both academic US institutions have developed a method of analyzing the content of these isotopes, which can reduce the detection limit is ten times as compared to the most sensitive of the above methods are available .

Physical chemist at Rice University (USA) is produced nanodiamonds and other forms of carbon nanotubes by bombarding a target moving at tremendous speeds. Nanodiamonds, unfortunately, will not make anyone fabulously rich, but they will help engineers in the creation of structures that can resist the introduction of bodies moving at high speeds, such as micrometeorites, when it comes to skin of the spacecraft. These diamonds are the result of a detailed study of the ballistic break carbon nanotubes, moving at different speeds. In the new study Pulikel Ajayan of Rice and Douglas Galvão from the University of Campinas, Brazil, placed multi-walled carbon nanotubes, spherical granules and shoots these granules on an aluminum target of a two-stage gun on light gases, as set out in the laboratory of Rice University, and then analyzed the results of the pellets clashes with the target at different speeds.

The central energy source of mysterious pulsating high-brightness X-ray sources (Ultra Luminous X-ray sources, ULX) may be a neutron star according to calculations made by the research team led by Tomohisa Kawashima from the National Astronomical Observatory of Japan. ULX-sources are the very bright X-ray sources, which are connected, as previously thought, with black holes. However, in 2014 the X-ray Observatory, NASA NuSTAR discovered unexpected periodic pulsating radiation emitted by the object ULX-called M82 X-2.

Hubble shears a woolly galaxy

This new image of the spiral galaxy NGC 3521 from the NASA/ESA Hubble Space Telescope is not out of focus. Instead, the galaxy itself has a soft, woolly appearance as it a member of a class of galaxies known as flocculent spirals.

Like other flocculent galaxies, NGC 3521 lacks the clearly defined, arcing structure to its spiral arms that shows up in galaxies such as Messier 101, which are called grand design spirals. In flocculent spirals, fluffy patches of stars and dust show up here and there throughout their discs. Sometimes the tufts of stars are arranged in a generally spiralling form, as with NGC 3521, but illuminated star-filled regions can also appear as short or discontinuous spiral arms.

About 30 percent of galaxies share NGC 3521's patchiness, while approximately 10 percent have their star-forming regions wound into grand design spirals.

NGC 3521 is located almost 40 million light-years away in the constellation of Leo (The Lion). The British astronomer William Herschel discovered the object in 1784. Through backyard telescopes, NGC 3521 can have a glowing, rounded appearance, giving rise to its nickname, the Bubble Galaxy.

Carina Nebula a tempestuous stellar nursery

Composed of gas and dust, the pictured pillar resides in a tempestuous stellar nursery called the Carina Nebula, located 7500 light-years away in the southern constellation of Carina.

Taken in visible light, the image shows the tip of the three-light-year-long pillar, bathed in the glow of light from hot, massive stars off the top of the image. Scorching radiation and fast winds (streams of charged particles) from these stars are sculpting the pillar and causing new stars to form within it. Streamers of gas and dust can be seen flowing off the top of the structure.

Hubble's Wide Field Camera 3 observed the Carina Nebula on 24-30 July 2009. WFC3 was installed aboard Hubble in May 2009 during Servicing Mission 4. The composite image was made from filters that isolate emission from iron, magnesium, oxygen, hydrogen and sulphur.

These Hubble observations of the Carina Nebula are part of the Hubble Servicing Mission 4 Early Release Observations.

In Argentina, we found a huge meteorite weighing more than 30 tons. The space object is found in the southwest of the province of Chaco. The researchers said that the findings weight 30.8 tons. Heavenly body was found in the zone of Campo del Cielo, where four thousand years ago was a meteor rain. According to Argentine scientists, to this point, we found only 35% of space objects that have fallen in the region. Astronomers searched for the meteorite a few months, but they did not anticipate that it would be so big. Meteorite may be one of the largest space objects found on Earth.

Star on a Hubble diet

The star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 that extends one degree on the sky in the direction of the Scorpius constellation. Part of the nebula is ionised by the youngest (bluest) heavy stars in Pismis 24. The intense ultraviolet radiation from the blazing stars heats the gas surrounding the cluster and creates a bubble in NGC 6357. The presence of these surrounding gas clouds makes probing into the region even harder.

One of the top candidates for the title of "Milky Way stellar heavyweight champion" was, until now, Pismis 24-1, a bright young star that lies in the core of the small open star cluster Pismis 24 (the bright stars in the Hubble image) about 8,000 light-years away from Earth. Pismis 24-1 was thought to have an incredibly large mass of 200 to 300 solar masses. New NASA/ESA Hubble measurements of the star, have, however, resolved Pismis 24-1 into two separate stars, and, in doing so, have "halved" its mass to around 100 solar masses.

Variable star, with light echo

This Hubble image shows RS Puppis, a type of variable star known as a Cepheid variable. As variable stars go, Cepheids have comparatively long periods — RS Puppis, for example, varies in brightness by almost a factor of five every 40 or so days.

RS Puppis is unusual; this variable star is shrouded by thick, dark clouds of dust enabling a phenomenon known as a light echo to be shown with stunning clarity.

These Hubble observations show the ethereal object embedded in its dusty environment, set against a dark sky filled with background galaxies.

Locked in a deadly embrace - Two galaxies spar with each other

The NASA/ESA Hubble Space Telescope has snapped the best ever image of the Antennae Galaxies. Hubble has released images of these stunning galaxies twice before, once using observations from its Wide Field and Planetary Camera 2 (WFPC2) in 1997, and again in 2006 from the Advanced Camera for Surveys (ACS). Each of Hubble’s images of the Antennae Galaxies has been better than the last, due to upgrades made during the famous servicing missions, the last of which took place in 2009.

The galaxies — also known as NGC 4038 and NGC 4039 — are locked in a deadly embrace. Once normal, sedate spiral galaxies like the Milky Way, the pair have spent the past few hundred million years sparring with one another. This clash is so violent that stars have been ripped from their host galaxies to form a streaming arc between the two. In wide-field images of the pair the reason for their name becomes clear — far-flung stars and streamers of gas stretch out into space, creating long tidal tails reminiscent of antennae.

This new image of the Antennae Galaxies shows obvious signs of chaos. Clouds of gas are seen in bright pink and red, surrounding the bright flashes of blue star-forming regions — some of which are partially obscured by dark patches of dust. The rate of star formation is so high that the Antennae Galaxies are said to be in a state of starburst, a period in which all of the gas within the galaxies is being used to form stars.

This cannot last forever and neither can the separate galaxies; eventually the nuclei will coalesce, and the galaxies will begin their retirement together as one large elliptical galaxy.

This image uses visible and near-infrared observations from Hubble’s Wide Field Camera 3 (WFC3), along with some of the previously-released observations from Hubble’s Advanced Camera for Surveys (ACS).
