METEOR MISSES GALAXY Image Credit: Aman Chokshi

The galaxy was never in danger. For one thing, the Triangulum galaxy (M33), pictured, is much bigger than the tiny grain of rock at the head of the meteor. For another, the galaxy is much farther away -- in this instance 3 million light years as opposed to only about 0.0003 light seconds. Even so, the meteor's path took it angularly below the galaxy. Also the wind high in Earth's atmosphere blew the meteor's glowing evaporative molecule train away from the galaxy, in angular projection. Still, the astrophotographer was quite lucky to capture both a meteor and a galaxy in a single exposure -- which was subsequently added to two other images of M33 to bring up the spiral galaxy's colors. At the end, the meteor was gone in a second, but the galaxy will last billions of years.

N11: STAR CLOUDS OF THE LMC Image Credit: NASA, ESA; Acknowledgement: Josh Lake

Massive stars, abrasive winds, mountains of dust, and energetic light sculpt one of the largest and most picturesque regions of star formation in the Local Group of Galaxies. Known as N11, the region is visible on the upper right of many images of its home galaxy, the Milky Way neighbor known as the Large Magellanic Clouds (LMC). The featured image was taken for scientific purposes by the Hubble Space Telescope and reprocessed for artistry by an amateur to win a Hubble's Hidden Treasures competition. Although the section imaged above is known as NGC 1763, the entire N11 emission nebula is second in LMC size only to the Tarantula Nebula. Compact globules of dark dust housing emerging young stars are also visible around the image. A new study of variable stars in the LMC with Hubble has helped to recalibrate the distance scale of the observable universe, but resulted in a slightly different scale than found using the pervasive cosmic microwave background.

SOUTHERN CROSS TO ETA CARINAE Image Credit & Copyright: Carlos Fairbairn

Tracking along the southern Milky Way this beautiful celestial mosaic was recorded under dark Brazilian skies. Spanning some 20 degrees it actually starts with the dark expanse of the Coalsack nebula at the lower left, tucked under an arm of the Southern Cross. That compact constellation is topped by bright yellowish Gamma Crucis, a cool giant star a mere 88 light-years distant. A line from Gamma Crucis through the blue star at the bottom of the cross, Alpha Crucis, points toward the South Celestial Pole. Follow the Milky Way to the right and your gaze will sweep across IC 2948, popularly known as the Running Chicken nebula, before it reaches Eta Carinae and the Carina Nebula near the right edge of the frame. About 200 light-years across, the Carina Nebula is a star forming region much larger than the more northerly stellar nursery the Orion Nebula. The Carina Nebula lies around 7,500 light-years from Earth along the plane of the Milky Way.

THE GALAXY, THE JET, AND THE BLACK HOLE Image Credit: NASA, JPL-Caltech, Event Horizon Telescope Collaboration

Bright elliptical galaxy Messier 87 (M87) is home to the supermassive black hole captured by planet Earth's Event Horizon Telescope in the first ever image of a black hole. Giant of the Virgo galaxy cluster about 55 million light-years away, M87 is the large galaxy rendered in blue hues in this infrared image from the Spitzer Space telescope. Though M87 appears mostly featureless and cloud-like, the Spitzer image does record details of relativistic jets blasting from the galaxy's central region. Shown in the inset at top right, the jets themselves span thousands of light-years. The brighter jet seen on the right is approaching and close to our line of sight. Opposite, the shock created by the otherwise unseen receding jet lights up a fainter arc of material. Inset at bottom right, the historic black hole image is shown in context, at the center of giant galaxy and relativistic jets. Completely unresolved in the Spitzer image, the supermassive black hole surrounded by infalling material is the source of the enormous energy driving the relativistic jets from the center of active galaxy M87.

FIRST LIKELY MARSQUAKE HEARD BY NASA'S INSIGHT

This video and audio illustrates a seismic event detected by NASA's InSight on April 6, 2019, the 128th Martian day, or sol, of the mission. Three distinct kinds of sounds can be heard, all of them detected as ground vibrations by the spacecraft's seismometer, called the Seismic Experiment for Interior Structure (SEIS): There's noise from Martian wind; the seismic event itself; and the spacecraft's robotic arm as it moves to take pictures.

This event is the first likely marsquake recorded by the InSight team. Several other seismic events have been recorded but are much more ambiguous than this signal.

The audio underscores just how seismically noisy the Martian surface can be and was produced from two sets of sensors included with SEIS. You can hear sounds from the Very Broad Band sensors from your left speakers and sounds from the Short Period sensors from your right speakers. Audio from both sets of sensors have been sped up by a factor of 60; the actual vibrations on Mars would not have been audible to the human ear. Playback on headphones or speaker system recommended for best experience.

SAHARIAN DUST MAKES UNIFORMLY OPAQUE SKY IN CENTRAL ITALY Taken by a.i. on April 26, 2019 @ Mont Gargano, Italy

From Mont Gargano, same latitude as Rome. The sky is gray, the sun barely visible. Phenomenon lasting since some days, the other day a tiny rain coated brown my car. The farther mountains in the landscape are some 5 Km distant.

A SAHARA SUNSET ... IN FINLAND

This week, something strange has been happening to the air in Europe. Dust is blowing across the continent's landscape, coating cars, cities, and snow-capped mountain peaks with a layer of red grit. The Sahara desert is to blame. Unusual weather has carried plumes of North African dust across Europe, with some clouds reaching as far north as Finland. Yesterday, in the Finnish Lapland, Thomas Kast witnessed tendrils of dust in the sunset:

"I was driving north in late afternoon, when the sun started to be visible through what I thought at first to be thin clouds," says Kast. "Then I remembered an article about Sahara dust being in the skies of the Lapland. About 30 minutes before sunset, the solar disk was dark enough for me to see lines of the sand clouds in it. It was a magical sight, something I haven't seen before."

Dust forecast maps prepared by the University of Athens show the air clearing in Europe by April 27-28, albeit with some residual dustiness over Greenland. Crazy sunsets may continue there for some days to come.

http://forecast.uoa.gr/dustindx.php

As winds shift, the dust will move away from Europe and toward the Atlantic, blowing an even bigger plume toward South America. This is not, in fact, unusual. Every year more than 200 million tons of dust blow from Saharan Africa to the Americas. The dust helps build beaches in the Caribbean, fertilizes soils in the Amazon, and likely plays a role in the suppression of hurricanes.

"WAKE ME UP" AVICII COVER (FEAT. FLEURIE) // PRODUCED BY TOMMEE PROFITT ♥ ♪

Feeling my way through the darkness

Guided by a beating heart

I can't tell where the journey will end

But I know where to start

They tell me I'm too young to understand

They say I'm caught up in a dream

Well, life will pass me by

If I don't open up my eyes

Well, that's fine by me

So wake me up when it's all over

When I'm wiser and I'm older

All this time I was finding myself

And I didn't know I was lost

So wake me up when it's all over

When I'm wiser and I'm older

All this time I was finding myself

And I didn't know I was lost

I tried carrying the weight of the world

But I only have two hands

Hope I get the chance to travel the world

But I don't have any plans

Wish that I could stay forever this young

Not afraid to close my eyes

Life's a game made for everyone

And love is the prize

So wake me up when it's all over

When I'm wiser and I'm older

All this time I was finding myself

And I didn't know I was lost

So wake me up when it's all over

When I'm wiser and I'm older

All this time I was finding myself

And I, I didn't know I was lost

I didn't know I was lost

I didn't know I was lost

I didn't know I was lost

I didn't know, I didn't know

Sintiendo mi camino a través de la oscuridad,
guiado por un corazón latiendo,
no sé decir dónde terminará el viaje,
pero sé por dónde empezar.
Me dicen que soy demasiado joven para entenderlo,
dicen que estoy atrapado en un sueño,
bueno, la vida me pasará de largo,
si no abro bien los ojos,
bueno, por mí está bien.

Así que despiértame cuando todo haya terminado,
cuando sea más sabio y más viejo,
todo este tiempo, estuve buscándome a mí mismo,
y no sabía que estaba perdido.

Así que despiértame cuando todo haya terminado,
cuando sea más sabio y más viejo,
todo este tiempo, estuve buscándome a mí mismo,
y no sabía que estaba perdido.

Intenté llevar el peso del mundo,
pero solo tengo dos manos,
espero tener la oportunidad de viajar (por) el mundo,
pero no tengo ningún plan.
Desearía poder quedarme así de joven para siempre,
no temo cerrar los ojos,
la vida es un juego hecho para todos,
y el amor es el premio.

Así que despiértame cuando todo haya terminado,
cuando sea más sabio y más viejo,
todo este tiempo, estuve buscándome a mí mismo,
y no sabía que estaba perdido.

Así que despiértame cuando todo haya terminado,
cuando sea más sabio y más viejo,
todo este tiempo, estuve buscándome a mí mismo,
y yo, yo no sabía que estaba perdido.

No sabía que estaba perdido,
no sabía que estaba perdido,
no sabía que estaba perdido,
no lo sabía, no lo sabía.

SUNSET WITH SAHARA DUST LINES Taken by Thomas Kast on April 25, 2019 @ Muonio, Lapland, Finland

I was driving towards North and in late afternoon, the sun disk started to be visible through - what I thought first - thin clouds. Then I remembered an article about the Sahara dust or sand being in the skies in Lapland.
Around half an hour before sunset, the sun disk was dark enough for me to see lines of the sand clouds in it. It was a magical sight, something I havent seen before.
Luckily Northern spring is early and so the lake was partly melted already, making for wonderful reflections.

LYRID FIREBALLS OVER DORF MILL Taken by Ruslan Merzlyakov on April 23, 2019 @ Dronninglund, Denmark

After my buddy Mikkel Schmidt nearly lost both of his shoes in the muddy swamp (as we wanted to photograph the mill from the other side with the Milky Way), we went back to the starting point - otherwise, I didnt really expect to get anything interesting from this location.

3 brights Lyrids from the timelapse (25 minutes, first hour of Apr. 23rd), we saw more and much brighter, but outside our cameras view field.

HUBBLE SPOTS FLOCK OF COSMIC DUCKS Hubble image of Messier 11

This star-studded image shows us a portion of Messier 11, an open star cluster in the southern constellation of Scutum (the Shield). Messier 11 is also known as the Wild Duck Cluster, as its brightest stars form a “V” shape that somewhat resembles a flock of ducks in flight.

Messier 11 is one of the richest and most compact open clusters currently known. By investigating the brightest, hottest main sequence stars in the cluster, astronomers estimate that it formed roughly 220 million years ago. Open clusters tend to contain fewer and younger stars than their more compact globular cousins, and Messier 11 is no exception: at its center lie many blue stars, the hottest and youngest of the cluster’s few thousand stellar residents.

The lifespans of open clusters are also relatively short compared to those of globular ones; stars in open clusters are spread farther apart and are thus not as strongly bound to each other by gravity, causing them to be more easily and quickly drawn away by stronger gravitational forces. As a result, Messier 11 is likely to disperse in a few million years as its members are ejected one by one, pulled away by other celestial objects in the vicinity.

Messier 11 is featured in Hubble’s Messier catalog, which includes some of the most fascinating objects that can be observed from Earth’s Northern Hemisphere. See the NASA-processed image and other Messier objects at: https://www.nasa.gov/content/goddard/hubble-s-messier-catalog.

PAN-STARRS ACROSS THE LAGOON Image Data Credit: Pan-STARRS, Eric Coles, Martin Pugh - Processing: Eric Coles

Ridges of glowing interstellar gas and dark dust clouds inhabit the turbulent, cosmic depths of the Lagoon Nebula. Also known as M8, the bright star forming region is about 5,000 light-years distant. But it still makes for a popular stop on telescopic tours of the constellation Sagittarius, toward the center of our Milky Way Galaxy. Dominated by the telltale red emission of ionized hydrogen atoms recombining with stripped electrons, this stunning view of the Lagoon is over 100 light-years across. At its center, the bright, compact, hourglass shape is gas ionized and sculpted by energetic radiation and extreme stellar winds from a massive young star. In fact, the many bright stars of open cluster NGC 6530 drift within the nebula, just formed in the Lagoon several million years ago. Broadband image data from Pan-STARRS (Panoramic Survey Telescope & Rapid Response System) was combined with narrowband data from amateur telescopes to create this wide and deep portrait of the Lagoon Nebula.

SAHARA DUST SUNRISE Taken by Ian Carstairs on April 23, 2019 @ Harleston, Norfolk, UK

METEORS, COMET, AND BIG DIPPER OVER LA PALMA Image Credit & Copyright: Vincent Duparc

Meteor showers are caused by streams of solid particles, dust size and larger, moving as a group through space. In most cases, the orbits of these meteor streams can be identified with dust expelled from a comet. When the Earth passes through a stream, the particles leave brilliant trails through the night sky as they disintegrate in Earth's atmosphere. The meteor paths are all parallel to each other, but, like train tracks, the effect of perspective causes them to appear to originate from a radiant point in the distance. The featured image composite was taken during January's Quadrantid meteor shower from La Palma, one of Spain's Canary Islands, off the northwest coast of Africa. The Quadrantids radiant is visible just below the handle of the Big Dipper. A careful eye will also discern the faint green coma of Comet Wirtanen. Tonight is the peak of the modest Lyrid meteor shower, with several meteors per hour visible from dark locations with clear skies.
