Even after nearly 3 years of loyal service, the Hubble Area Telescope continues to run and supply spectacular pictures of the universes. As one of NASA’s Excellent Observatories, its observations of far-off galaxies, exoplanets, and the growth of deep space have actually had an innovative influence on astronomy, astrop... | 0.842568 | 3.799767 |
These days, consumers can take their pick from an impressive array of fabulous items of diamond jewellery. For example, they can head online to select princess cut diamond engagement rings. All they need is a little spare time and a web connection.
As long as they know where to look, they should be able to find the per... | 0.830061 | 3.131329 |
In addition to James K's answer, many gases exist in the disk of material that forms into planets. What's a gas as opposed to a liquid or solid also depends on temperature and pressure. The most abundant "gases" in our solar-system are hydrogen, helium, CO2, H2O, CH4, NH3, N2, O2, CO, Neon (and maybe some others I've o... | 0.84813 | 3.922052 |

NASA's two Voyager spacecraft show nothing's simple at the edges of the solar system.
After a three-decade journey away from Earth, the two Voyager spacecraft are approaching the outer edges of the solar system. To scientists' surprise, the satellites have revealed a region vastly different than previously modeled. The... | 0.841387 | 3.452901 |
(Inside Science) -- Terrestrial animals may owe a special debt to the sun and the moon. It may have been their combined pull on ancient Earth's oceans that helped primitive air-breathing fish gain a toehold on land, new research suggests.

There are a couple of man-made objects in space that almost everyone will know about: the International Space Station, the Hubble Space Telescope, Mars Science Laboratory Curiosity and maybe Voyager I and/or II. However, there is so much other man-made stuff in space it’s crazy (and it’s actually start... | 0.878362 | 3.604311 |
The Dark Side of the Universe
by Jan Smit and Renske Smit
To put us, as book reviewers, in context, like many scientists, we study our surroundings in an effort to understand where we came from. Jan, the historical geologist, likes to begin with the birth of our solar system 4.56 billion years ago. Before that, in his ... | 0.905366 | 3.635978 |
I am looking for basic data regarding red-shifting that comes with reliable measure of distance of the emitting star.
Red shift is usually measured for galaxies rather than individual stars. Unless a star has just gone supernova, it's usually not bright enough to be seen even w the world's most powerful telescopes at t... | 0.875891 | 3.468853 |
Behold: Arp 273 – a great interstellar battle featuring upper galaxy UGC 1810 and its smaller collisional neighbour UGC 1813. War is hell. To wit:
The overall shape of the UGC 1810 — in particular its blue outer ring — is likely a result of wild and violent gravitational interactions. The blue colour of the outer ring ... | 0.819331 | 3.220063 |
This image illustrates the four common states of matter: solid, liquid, gas, and plasma.
States of Matter
This figure shows the four common states of matter: solid, liquid, gas, and plasma.

DIALLING, sometimes called gnomonics, is a branch of applied mathematics which treats of the construction of sun-dials, that is, of those instruments, either fixed or portable, which determine the divisions of the day by the motion of the shadow of some object on which the sun's rays fall.
It must have been one of the ... | 0.838979 | 3.251505 |
Something abnormal is cruising toward us. Something little and cold and uncommonly quick. Nobody knows where it originated from, or where it is going. However, it’s not from around here. This is an interstellar comet – an old chunk of ice and gas and residue, framed on the solidified edges of a far off star, which some... | 0.885939 | 3.158974 |
In newly released footage from the University of Western Ontario, a bright, slow-moving fireball was captured in the skies near Toronto, Canada on December 12, 2011 by remote cameras watching for meteors. Although this meteor looks huge as it burns up in Earth’s atmosphere, astronomers estimate the rock to have been no... | 0.808608 | 3.192801 |

Does a permanently shadowed crater at the Moon’s South Pole harbor frozen water? Enough to supply a lunar outpost? How much ultraviolet and cosmic radiation would astronauts be exposed to if they stayed on the moon for a week or longer? Where are the best—and worst—landing sites on the Moon? These are some of the quest... | 0.85434 | 3.810709 |
Questions about electron degenerate stellar remnants.
A white dwarf, also known as a degenerate dwarf, is a type of stellar remnant. It forms from the pressured core during the death of medium stars not capable of exerting enough gravity to overcome electron resistance. White dwarfs have masses on average of about 0.5 ... | 0.823374 | 3.299677 |
Where there once was 158, there is now more… Globular clusters, that is. Thanks to ESO’s VISTA survey telescope at the Paranal Observatory in Chile, the Via Lactea (VVV) survey has cut through the gas and dust of the Milky Way to reveal the first star cluster that is far beyond our center. But keep your eyes on the pri... | 0.805851 | 3.065912 |

The Little Ice Age was a period of cooling that occurred after the Medieval Warm Period. Although it was not a true ice age, the term was introduced into scientific literature by François E. Matthes in 1939, it has been conventionally defined as a period extending from the 16th to the 19th centuries, but some experts p... | 0.837082 | 3.445516 |
Billions of years ago, Earth’s magnetic field may have gotten a jump-start from a turbulent magma ocean swirling around the planet’s core.
Our planet has generated its own magnetism for almost its entire history (SN: 1/28/19). But it’s never been clear how Earth created this magnetic field during the planet’s Archean E... | 0.840818 | 3.836205 |
According to ancient and medieval science, aether (//), also spelled æther or ether and also called quintessence, is the material that fills the region of the universe above the terrestrial sphere. The concept of aether was used in several theories to explain several natural phenomena, such as the traveling of light an... | 0.836825 | 3.811504 |

In just over one weeks time, Mercury will pass in front of the Sun. Although Mercury only covers 0.004% of the surface of the Sun, this is a rare event and hence worthwhile to have a closer look at, although you should, of course, never “look” at the Sun directly without proper protection.
As only one of three bodies i... | 0.863486 | 3.256135 |
The next NASA mission to Mars, the InSight lander, will include some additional experimental technology: the first deep-space CubeSats. Two small CubeSats will fly past the planet as the lander is descending through the atmosphere; this will be the first time CubeSats have been used in an interplanetary mission.

As intelligent as we are, as human’s we aren’t endowed with the most powerful of eyes. Sure, most of us can see the full glory of the ROYGBIV rainbow, but, it requires special devices for us to perceive specific frequencies of the electromagnetic spectrum.
