Astronomers discovered the first exoplanet in a habitable zone with water in its atmosphere

Astronomers discovered the first exoplanet in a habitable zone with water in its atmosphere

Astronomers discovered water vapor in the atmosphere of super-earth K2-18b, an exoplanet that is orbiting its host star in the habitable zone. According to scientists, k2-18b might potentially be the most habitable out of all exoplanets that have been discovered up until this day. The researchers published their findings in the science journal Nature Astronomy

First country has approved participation in constructing the largest telescope the world has ever known

First country has approved participation in constructing the largest telescope the world has ever known

The Dutch parlement has been the first to formally confirm participation in the assembly of the largest radio telescope the world has has ever known. The massive telescope might give us another opportunity to find out if we are alone in the universe!

Traces of One of the Oldest Stars in the Universe Found Inside Another Star!

Traces of One of the Oldest Stars in the Universe Found Inside Another Star!

Despite all we know about the formation and evolution of the Universe, the very early days are still kind of mysterious. With our knowledge of physics we can shed some light on the nature of the earliest stars, even though they’re almost certainly long gone.

Astronomers Uncover Dozens of Previously Unknown Ancient and Massive Galaxies

Astronomers Uncover Dozens of Previously Unknown Ancient and Massive Galaxies

For decades, astronomers have been trying to see as far as they can into the deep Universe. By observing the cosmos as it was shortly after the Big Bang, astrophysicists and cosmologists hope to learn all they can about the early formation of the Universe and its subsequent evolution. Thanks to instruments like the Hubble Space Telescope, astronomers have been able to see parts of the Universe that were previously inaccessible.

Virtual 'Universe Machine' Sheds Light on Galaxy Evolution

Virtual 'Universe Machine' Sheds Light on Galaxy Evolution

By creating millions of virtual universes and comparing them to observations of actual galaxies, a University of Arizona-led research team has made discoveries that present a powerful new approach for studying galaxy formation.

Kepler’s forgotten ideas about symmetry help explain spiral galaxies without the need for dark matter – new research

Kepler’s forgotten ideas about symmetry help explain spiral galaxies without the need for dark matter – new research

The 17th-century astronomer Johannes Kepler was the first to muse about the structure of snowflakes. Why are they so symmetrical? How does one side know how long the opposite side has grown? Kepler thought it was all down to what we would now call a “morphogenic field” – that things want to have the form they have. Science has since discounted this idea. But the question of why snowflakes and similar structures are so symmetrical is nevertheless not entirely understood.

Gaia Mission is Mapping Out the Bar at the Center of the Milky Way

Gaia Mission is Mapping Out the Bar at the Center of the Milky Way

Despite the many advancements made in the field of astronomy, astronomers still struggle to get an accurate assessment of the Milky Way Galaxy. Because we are embedded in its disk, it is much more difficult to assess its size, structure, and extent – unlike galaxies located millions (or billions) of light-years away. Luckily, thanks to improved instruments and tireless efforts, progress is being made all the time.

Hubble is the Ultimate Multitasker: Discovering Asteroids While it’s Doing Other Observations

It looks like a poster of the famous Hubble Deep Field, marked with white streaks by a child, or put away carelessly and scratched in the process. But it’s not. The white streaks aren’t accidents; they’re the paths of asteroids.

Hubble Finds Tiny “Electric Soccer Balls” in Space, Helps Solve Interstellar Mystery

Scientists using NASA’s Hubble Space Telescope have confirmed the presence of electrically-charged molecules in space shaped like soccer balls, shedding light on the mysterious contents of the interstellar medium (ISM) – the gas and dust that fills interstellar space.

New Instrument is Searching for Planets Around Alpha Centauri

New Instrument is Searching for Planets Around Alpha Centauri

Alpha Centauri is the closest star system to us, at 4.37 light-years (about 25 trillion miles) away. In 2016, astronomers discovered an exoplanet orbiting one of the three stars in the Alpha Centauri system. Spurred on by that discovery, the European Southern Observatory (ESO) has developed a new instrument to find any other planets that might be in the Alpha Centauri system, and it’s busy looking right now.

On the 25th of may a double asteroid came uncomfortably close to earth. Here’s what astronomers saw

On May 25th, 2019, a strange, double-asteroid (1999 KW4) flew past Earth at a distance and speed that is likely to make a lot of people nervous. As always, there was no danger, since the asteroid passed Earth at a minimum distance of 5.2 million km (3.23 million mi), over 15 times greater than the distance between Earth of the Moon, and its orbit is well-understood by scientists.

There’s a Ring of Cool Gas Wrapped Around the Milky Way’s Supermassive Black Hole

There’s a Ring of Cool Gas Wrapped Around the Milky Way’s Supermassive Black Hole

There’s a lot going on at the center of our galaxy. A supermassive black hole named Sagittarius A-Star resides there, drawing material in with its inexorable gravitational attraction. In that mind-bending neighborhood, where the laws of physics are stretched beyond comprehension, astronomers have detected a ring of cool gas.

NASA is building up a map of the entire sky seen in X-rays, line by line with its NICER experiment

NASA is building up a map of the entire sky seen in X-rays, line by line with its NICER experiment

In June of 2017, NASA’s Neutron Star Interior Composition Explorer (NICER) was installed aboard the International Space Station (ISS). The purpose of this instrument is to provide high-precision measurements of neutron stars and other super-dense objects that are on the verge of collapsing into black holes. NICER is also be the first instrument designed to test technology that will use pulsars as navigation beacons.
