Zooming in on The Cone Nebula: 60th Anniversary Image | ESO

Zooming in on The Cone Nebula: 60th Anniversary Image | ESO

This video starts from our location in the galaxy, showing the stellar and dusty band of the Milky Way. Zooming in towards it, we move to the constellation Monoceros (The Unicorn), next to Orion, where the large star-forming region of the NGC 2264 cluster can be found. Within this cluster, we find the pillar-like shape of the Cone Nebula.

 The dramatic new view of the nebula shown at the end of the video, showcases its dark and impenetrable cloudy appearance. The image was captured with the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument on ESO’s Very Large Telescope (VLT), and was released on the occasion of ESO’s 60th anniversary.

The Cone Nebula: 60th Anniversary Image | ESO

Happy 60th Anniversary to the European Southern Observatory!

The Cone Nebula is part of a star-forming region of space, NGC 2264, about 2,500 light-years away. Its pillar-like appearance is a perfect example of the shapes that can develop in giant clouds of cold molecular gas and dust, known for creating new stars. This dramatic new view of the nebula was captured with the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument on the European Southern Observatory’s Very Large Telescope (VLT), and released on the occasion of ESO’s 60th anniversary. 

Image Description: This image shows the Cone Nebula at the center of the picture taking up most of the frame. The shape of the dark nebulous cloud is that of a cone, pointing upwards. At the top and surrounding the cone are bright yellow stars of different sizes, tiny dots and bigger gassy spheres. To the left of the central figure, abstract dusty patterns are fading upwards. The top shines brightly, lit up by luminous stars.

Three Faces of Supernova Explosion over 11 Billion Years Ago | Hubble

Three Faces of Supernova Explosion over 11 Billion Years Ago | Hubble

Through a “trick” of light-bending gravity, the Hubble Space Telescope captured three different moments in the explosion of a very far-off supernova—all in one snapshot! The progenitor star exploded more than 11 billion years ago, when the Universe was less than a fifth of its current age of 13.8 billion years.

Einstein first predicted this phenomenon, called gravitational lensing, in his theory of general relativity. In this case, the immense gravity of the galaxy cluster Abell 370 acted as a cosmic lens, bending and magnifying the light from the more distant supernova located behind the cluster. 

The warping also produced multiple images of the explosion over different time periods that all arrived at Hubble simultaneously. They show the unfolding supernova over the course of a week.

Total Lunar Eclipse & NASA's Artemis I Moon Rocket | Kennedy Space Center

Total Lunar Eclipse & NASA's Artemis I Moon Rocket | Kennedy Space Center

The Moon is seen during a total lunar eclipse above NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard atop a mobile launcher at Launch Pad 39B, Tuesday, Nov. 8, 2022, at NASA’s Kennedy Space Center in Florida. NASA’s Artemis I flight test is the first integrated test of the agency’s deep space exploration systems: the Orion spacecraft, SLS rocket, and supporting ground systems. 

The first in a series of increasingly complex missions, Artemis I will be an uncrewed flight test that will provide a foundation for human deep space exploration, and demonstrate NASA's commitment and capability to extend human existence to the Moon and beyond.  It will travel 280,000 miles from Earth, thousands of miles beyond the Moon over the course of about a three-week mission. Orion will stay in space longer than any ship for astronauts has done without docking to a space station and return home faster and hotter than ever before.

On the Artemis III Mission, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

Gravitational Lensing: Magnifying the Universe's Distant Past | Hubble

Gravitational Lensing: Magnifying the Universe's Distant Past | Hubble

Space Sparks Episode 5: This Space Sparks Episode explores the concept of gravitational lensing. 

This effect is only visible in rare cases and only the best telescopes—including the NASA/ESA Hubble Space Telescope—can observe the results of gravitational lensing. The strong gravity of a massive object, such as a cluster of galaxies, warps the surrounding space, and light from distant objects travelling through that warped space is curved away from its straight-line path.

This video will highlight how Hubble's sensitivity and high resolution allows it to see details in these faint, distorted images of distant galaxies.

Stellar Birthplaces: Nebulas NGC 3603 & NGC 3576 (infrared) | ESO

Stellar Birthplaces: Nebulas NGC 3603 & NGC 3576 (infrared) | ESO

The image shows two cosmic clouds of purple with a golden orange glow towards their centers. The clouds are found separated from each other on each side of the image. The clouds stand out against a black background with a myriad of stars.

This is a new view of NGC 3603 (left) and NGC 3576 (right), two stunning nebulas imaged with the European Southern Observatory’s Visible and Infrared Survey Telescope for Astronomy (VISTA). This infrared image peers through the dust in these nebulas, revealing details hidden in optical images. 

NGC 3603 and NGC 3576 are 22,000 and 9,000 lightyears away from us, respectively. Inside these extended clouds of dust and gas, new stars are born, gradually changing the shapes of the nebulas via intense radiation and powerful winds of charged particles. Given their proximity, astronomers have the opportunity to study the intense star formation process that is as common in other galaxies but harder to observe due to the vast distances.

The two nebulas were cataloged by John Frederick William Herschel in 1834 during a trip to South Africa, where he wanted to compile stars, nebulas and other objects in the sky of the southern hemisphere. This catalogue was then expanded by John Louis Emil Dreyer in 1888 into the New General Catalogue, hence the NGC identifier in these and other astronomical objects.

Investigating a Made-to-Measure Galaxy: NGC 7038 in Indus | Hubble

Investigating a Made-to-Measure Galaxy: NGC 7038 in Indus | Hubble

The spiral arms of the galaxy NGC 7038 wind languidly across this image from the NASA/European Space Agency Hubble Space Telescope. NGC 7038 lies around 220 million light-years from Earth in the southern constellation Indus. This image portrays an especially rich and detailed view of a spiral galaxy, and exposes a huge number of distant stars and galaxies around it. This is because it is made from a combined 15 hours worth of Hubble time focused on NGC 7038 and collecting light. So much data indicates that this is a valuable target, and indeed, NGC 7038 has been particularly helpful to astronomers measuring distances at vast cosmic scales.

Image Description: An enormous spiral galaxy fills half of the frame, in the center. It is oval-shaped, with four blue spiral arms winding around it. The galaxy’s centre shines brightly with pale yellow light. Thin strands of orange dust are spread around the centre, following the paths of the arms. Above and below the galaxy, very many small stars and galaxies are visible on the black background.

The distances to astronomical objects are determined using an interconnected chain of measurement techniques called the Cosmic Distance Ladder. Each rung in the ladder is calibrated by earlier steps, based on measurements of objects closer to us. This makes the accuracy of distances at the largest scales dependent on how accurately distances to nearby objects can be determined. Hubble inspected NGC 7038 with its Wide Field Camera 3 to calibrate two of the most common distance measurement techniques: type 1A supernovae and Cepheid variables. 

One of Hubble's original science goals was to accurately establish distances to night-sky objects, and over its three decades of operation Hubble’s increasingly precise distance measurements have contributed to one of the most intriguing unsolved problems in astronomy. Distance measurements are used to derive a quantity known as the Hubble constant, which captures how fast the Universe is expanding. As astronomer’s measurements of the Hubble constant have become more precise, their value has become increasingly inconsistent with the value of the Hubble Constant derived from observations of the Big Bang’s afterglow. Astronomers have been unable to explain the mismatch between the two values of the Hubble constant, which suggests that a new discovery in cosmology is waiting to be made.
