Launched on April 24, 1990, the Hubble Space Telescope remains a major symbol for NASA more than 30 years later. Here’s a look at some stellar images from the Hubble.
Pillars of Creation
After the Hubble’s 30 years in space, this image remains one of its most iconic. The Pillars of Creation depicts a jet-like feature that astronomers say has grown by about 96.5 billion kilometres, based on comparisons of pictures taken between 1995 and 2014.

Marking the telescope’s three decades in space, NASA unveiled a new image taken by Hubble’s Wide Field Camera 3. It shows how young, energetic, massive stars illuminate and sculpt their birthplace with powerful winds and searing ultraviolet radiation. The image, nicknamed the Cosmic Reef because it resembles an undersea world, shows a giant red nebula and a smaller blue one that create a huge star-forming region.

Hubble Ultra Deep Field
In this 2012 image of hundreds of galaxies, the Hubble provides a display of a phenomenon known as gravitational lensing.
The telescope captured a region six billion light-years away containing the galaxy cluster Abell 370, one of the first galaxy clusters in which astronomers observed gravitational lensing, the warping of space-time by the cluster’s gravitational field that distorts the light from galaxies far behind it.

This 2015 photo features a stellar nursery of about 3,000 stars called Westerlund 2, located about 20,000 light-years from the planet Earth in the constellation Carina.
In 2006, this Hubble-captured image of the merging Antennae galaxies offered one of the first high-resolution glimpses of the birth of billions of stars. The brightest and most dense areas of the image show super star clusters representing some of the newest material in space.

Images of Eta Carinae, a dying star in our Milky Way galaxy, led scientists to conclude in a 2007 article in the journal Nature that a similarly sized star went supernova some 78 million light-years from Earth and wiped out a star 100 times the size of our sun.
U Camelopardalis, or U Cam for short, is a star nearing the end of its life located in the Giraffe constellation near the celestial North Pole. As it begins to run low on fuel, instability within the star’s core creates coughs of helium gas every few thousand years. This image was captured by Hubble in 2012.

Jupiter’s polar light
Jupiter, the largest planet in the solar system, is best known for its colourful storms, the most famous being the Great Red Spot. Using the ultraviolet capabilities of Hubble, astronomers have focused on another feature of the planet: auroras — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the solar system.

From ground-based telescopes, this cosmic object — the glowing remains of a dying, sun-like star — resembles the head and thorax of an ant.
This image, released in 2003, shows the so-called ant nebula, otherwise known as Menzel 3, and reveals a pair of fiery lobes protruding from the dying star.
SpaceX Sent NASA Astronauts Into Orbit Using Linux – Futurism
This past weekend, Elon Musk-led private space company SpaceX made history by launching a pair of NASA astronauts into orbit, an accomplishment that could upset the balance of the international space industry.
According to a terrific breakdown by ZDNet, the historic launch also contributed to a shift in power from proprietary software to open source — by running the Falcon 9 rocket on a version of the open source operating system Linux.
Kernel Space Program
The unspecified version of Linux, according to ZDNet, runs on three dual-core x86 processors — a redundancy system that keeps the astronauts safe by making sure all three units agree before executing each command.
ZDNet also pointed to a 2013 Reddit post in which SpaceX employees confirmed that Dragon and Falcon 9 both on Linux.
SpaceX isn’t the first group to bring open source software into orbit.
The International Space Station itself, where the NASA astronauts launched by SpaceX are now residing, reportedly switched to Linux from Microsoft’s proprietary Windows operating system in 2013.

How to watch the 'strawberry moon' eclipse from anywhere Friday – CNET
Get ready to look to the night sky on Friday. A full “strawberry moon” is on the calendar, and it will come with an understated partial eclipse for some parts of the world. While the moon will be at its absolute fullest on Friday around noon PT, you’ll have several opportunities to enjoy the view. The moon will still look full from early Thursday morning through early Sunday morning, NASA said Monday.
North America will miss the eclipse, but the Virtual Telescope Project will livestream the lunar event from Italy above a view of the Rome skyline. Mark your calendar for noon PT on Friday, June 5, and visit the project’s web TV page to join in.
A penumbral eclipse is much more subtle than a total eclipse. The moon slips through the Earth’s outer (penumbral) shadow, which can trigger a slight darkening of the moon. If you didn’t know it was happening, you might miss it. A partial penumbral eclipse like the one on Friday makes it even harder to spot a difference.
Denizens of the moon, however, would notice the effects. “For spacecraft at the Moon such as the Lunar Reconnaissance Orbiter (LRO), the reduction in solar power is noticeable,” NASA said.
Unfortunately, the “strawberry” nickname for the June full moon doesn’t refer to a color, but seems to be an old reference to the strawberry harvest season. NASA’s Gordon Johnston rounded up a list of alternative names for this month’s moon, including mead moon, honey moon, hot moon and planting moon.
Even if the eclipse is too faint to detect, you can still take a moment to bask in the light of a lovely full moon this week.
