nasa: The Hubble Space Telescope has some amazing superpowers,

The Hubble Space Telescope has some amazing superpowers, specifically when it comes to observing innumerable galaxies flung across time and space. A stunning example is a galaxy cluster called Abell 370. Located approximately 4 billion light-years away, this galaxy cluster contains an assortment of several hundred galaxies tied together by the mutual pull of gravity. Photographed in a combination of visible and near-infrared light, the brightest and largest galaxies are the yellow-white, massive, elliptical galaxies containing many hundreds of billions of stars EACH! Spiral galaxies have younger populations of stars and are bluish. Mysterious-looking arcs of blue light are distorted images of remote galaxies behind the cluster. The cluster acts as a huge lens in space that magnifies and stretches images of background galaxies like a funhouse mirror. Credits: NASA/ESA/STScI cluster telescope year hubble

nasa: Hubble sees a force awakening in a newborn

Hubble sees a force awakening in a newborn star…What looks like a double-sided lightsaber is actually a cosmic object known as HH 24. This celestial lightsaber does not lie in a galaxy far, far away, but rather inside our home galaxy, the Milky Way. It's inside a turbulent birthing ground for new stars known as the Orion B molecular cloud complex, located 1,350 light-years away. Just to the right of the cloaked star, a couple of bright points are young stars peeking through and showing off their own faint lightsabers — including one that has bored a tunnel through the cloud towards the upper-right side of the picture.

nasa: What’s up in the night sky this

What’s up in the night sky this May? Jupiter climbs higher in the southeast sky earlier in the evening this month. This means that telescope viewers don’t need to wait until midnight to get good views of the planet. You can enjoy Jupiter through binoculars too! Saturn is now visible before midnight, rising around 11:30 p.m. early in the month and by 9:30 p.m. later in the month. The best time to see Saturn is when it’s highest in the sky, that’s after midnight this month and before midnight in June. Through a telescope, you may even see some of Saturn’s cloud bands!Check it out… Credit: NASA/JPL s

nasa: It

It's springtime and the deployed primary mirror of our James Webb Space Telescope looks like a spring flower in full bloom. In this photo, technicians lifted the telescope using a crane and moved it inside a clean room at our Goddard Space Flight Center in Greenbelt, Maryland. Once launched into space, the Webb telescope’s 18-segmented gold mirror is specially designed to capture infrared light from the first galaxies that formed in the early universe, and will help the telescope peer inside dust clouds where stars and planetary systems are forming today. The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Credits: NASA/Desiree Stover telescope webb

nasa: In space, being outshone is an occupational hazard.

In space, being outshone is an occupational hazard. This Hubble Space Telescope image captures a galaxy named NGC 7250. Despite being remarkable in its own right — it has bright bursts of star formation and recorded supernova explosions— it blends into the background somewhat thanks to the gloriously bright star hogging the limelight next to it. The bright object seen in this Hubble image is a single and little-studied star named TYC 3203-450-1, located in the constellation of Lacerta (The Lizard). The star is much closer than the much more distant galaxy. Only this way can a normal star outshine an entire galaxy, consisting of billions of stars. Astronomers studying distant objects call these stars “foreground stars” and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study.

The magnetic field lines between a pair of active regions formed a beautiful set of swaying arches, seen in this footage captured by our Solar Dynamics Observatory on April 24-26, 2017. These arches, which form a connection between regions of opposite magnetic polarity, are visible in exquisite detail in this wavelength of extreme ultraviolet light. Extreme ultraviolet light is typically invisible to our eyes, but is colorized here in gold. This video covers almost two days of activity. Credits: NASA/SDO observatory craft

nasa: We did it! Our Cassini spacecraft successfully dove

We did it! Our Cassini spacecraft successfully dove through the gap between Saturn and its rings – an area previously unexplored by any spacecraft! These unprocessed images show features in Saturn’s atmosphere from closer than ever before! These views were captured by our Cassini spacecraft during its first Grand Finale dive between the planet and its rings on April 26, 2017. As Cassini dove through the gap, it came within about 1,900 miles (3,000 kilometers) of Saturn’s cloud tops (where the air pressure is 1 bar – comparable to the atmospheric pressure of Earth at sea level) and within about 200 miles (300 kilometers) of the innermost visible edge of the rings.

[Illustration] 'Iceball' planet discovered! Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, however, because its star is so faint. But the discovery adds to scientists' understanding of the types of planetary systems that exist beyond our own. This 'iceball' planet is the lowest-mass planet ever found through microlensing, a technique that facilitates the discovery of distant objects by using background stars as flashlights. When a star crosses precisely in front of a bright star in the background, the gravity of the foreground star focuses the light of the background star, making it appear brighter. A planet orbiting the foreground object may cause an additional blip in the star's brightness. In this case, the blip only lasted a few hours. This technique has found the most distant known exoplanets from Earth, and can detect low-mass planets that are substantially farther from their stars than Earth is from our sun.

nasa: Cosmic Bubbles: This entrancing image shows a few

Cosmic Bubbles: This entrancing image shows a few of the tenuous threads that comprise a faint and wispy shell of gas located 5,200 light-years away. This large bubble-like structure wrapped around an extremely large, bright type of star known as a Wolf-Rayet Star - this particular star is called EZ Canis Majoris. These type of stars are among the brightest and most massive stars in the universe, tens of times more massive than our own sun, and they represent the extremes of stellar evolution. Thick winds continually poured off the progenitors of such stars, flooding their surroundings and draining the outer layers of the Wolf-Rayet stars. The fast wind of a Wolf-Rayet star therefore sweeps up the surrounding material to form bubbles of gas. Beautiful as these cosmic bubbles are, they are fleeting. The same stars that form them will also cause their death, eclipsing and subsuming them in violent supernova explosions. Credit: ESA/Hubble & NASA beyond

Congrats, Peggy! Flight Director Brian Smith, Capcom astronaut Jessica Meir along with astronaut Jeff Williams monitor activities in Mission Control as President Donald Trump, First Daughter Ivanka Trump and NASA astronaut Kate Rubins make a special Earth-to-space call from the Oval Office to personally congratulate NASA astronaut Peggy Whitson for her record-breaking stay aboard the International Space Station ( ). Whitson officially set the U.S. record for most cumulative days in space. She is the first woman to command the space station twice, and holds the record for most spacewalks conducted by a female astronaut. Photo Credit: NASA/Robert Markowitz

nasa: Cascading Loops: An active region that had just

Cascading Loops: An active region that had just rotated into view blasted out a coronal mass ejection, which was immediately followed by a bright series of post-coronal loops seeking to reorganize that region's magnetic field (April 19, 2017). We have observed this phenomenon numerous times, but this one was one of the longest and clearest sequences we have seen in years. The bright loops are actually charged particles spinning along the magnetic field lines. The action was captured in a combination of two wavelengths of extreme ultraviolet light over a period of about 20 hours. Credit: Solar Dynamics Observatory, NASA beyond science
